Cross-Chain Bridge for Robinhood & Stable Chain

What is Titan Bridge?

Titan Bridge is a non-custodial bridge aggregator developed by Titan that automatically routes transfers across multiple bridge providers to optimise speed, cost, and reliability. In practice, that means you choose a source chain, a destination chain, an asset, and an amount; Titan Bridge queries several routing providers, compares the results, and returns a single transaction for your own wallet to sign. It moves both native assets (ETH, BNB, USDT0) and ERC-20 tokens between Robinhood Chain (chain ID 4663), Stable Chain (chain ID 988), Ethereum (1), BNB Chain (56), and Base (8453), in any direction.

Titan Bridge is not itself a bridge protocol. It is an aggregation layer that sits above existing bridges and decides which one to use for each transfer. This distinction matters: a bridge protocol moves value using one fixed mechanism, whereas an aggregator can pick whichever protocol is cheapest, fastest, and actually available for your exact route at the moment you request it.

Why Titan Bridge exists

Robinhood Chain and Stable Chain are newer EVM chains, and liquidity for bridging into and out of them is fragmented across several protocols. No single bridge reliably serves every asset and every pair at all times: one may have the cheapest route for ETH from Base today, another the only route for a stablecoin from BNB Chain tomorrow. A user who commits to one bridge protocol is exposed to that protocol's specific liquidity gaps, downtime, and pricing.

Titan Bridge exists to remove that decision from the user. Rather than asking you to know which protocol serves your route, it checks multiple providers on every request and routes through whichever one wins on price and speed - and if the first has no route, it automatically tries another before telling you a pair is unavailable. The result is broader coverage and better pricing than any single underlying bridge, with none of the manual comparison.

How route aggregation works

When you enter a transfer, Titan Bridge sends the parameters - source chain, destination chain, token, amount, and your address - to its routing providers and receives back one or more candidate routes. A route is a concrete plan: which underlying bridge to use, the exact amount you will receive, the minimum guaranteed after slippage, the fees, and an estimated settlement time. Titan compares the candidate routes and surfaces the best one, showing you all of those numbers before you commit.

Only when you approve does anything touch your wallet. For an ERC-20 you first authorise the bridge contract to move the token (a one-time approval per token), then sign the bridge transaction itself; for a native asset it is a single signature. The transaction executes on the source chain, the underlying bridge protocol delivers the asset on the destination chain, and Titan tracks the settlement status live until the funds arrive. Titan never holds the funds at any step - the aggregation only selects the route.

Why aggregating multiple providers beats using one bridge

• Better pricing. Route costs differ by protocol, asset, amount, and live liquidity. Comparing providers per-request means you get the cheapest route available at that moment, not whatever one protocol happens to quote.
• Broader coverage.A pair that one protocol can't serve is often served by another. Aggregation plus an automatic fallback turns "no route" into "a route, from a different provider."
• Resilience. If a protocol has degraded liquidity or downtime, the aggregator simply routes around it. A single-protocol bridge has no such fallback.
• Speed.The fastest settlement path varies by route; the aggregator can prefer it instead of being locked to one protocol's mechanism and timing.
• One interface. The same wallet flow works for every chain and asset, instead of learning a different UI and trust model for each bridge.

Routing providers

Titan integrates two routers directly: LI.FI and Relay. LI.FI is itself an aggregator that selects among many underlying bridge protocols - including Across and Stargate - so those protocols are reached through LI.FI rather than integrated one-by-one. Relay is called directly as an automatic fallback. This is the full, honest set: Titan is a layer above these providers, not another bridge competing with them.

How route optimisation works

For each request, Titan optimises on the number that actually reaches you: the net receive amount after all fees, subject to a slippage bound and a settlement-time estimate. A route's cost is the sum of source-chain gas, the underlying bridge's own fee, and Titan's routing fee - all of which are already reflected in the quoted receive amount, so what you see is what arrives, within the slippage you accepted. Because these costs vary by route, amount, and live network conditions, the widget does not advertise a fixed rate: the live quote is the authoritative number, and it is shown before you sign.

Route availability for the smaller chains genuinely changes minute to minute on the underlying protocols' side. Titan retries automatically and checks its fallback provider before reporting a pair as unavailable; if a direct route still can't be found, bridging in two steps via a major chain such as Ethereum or Base is a reliable workaround.

Bridge architecture

Titan Bridge is an interface plus a routing layer. It holds no pooled liquidity and runs no bridge validators of its own; the value transfer is always executed by an established underlying protocol. The end-to-end path for a single transfer:

Your wallet (source chain)
   │  1. request quote  ──────────────►  Titan routing layer
   │                                        │  queries LI.FI (+ Relay fallback)
   │  2. best route + exact numbers  ◄──────┘
   │
   │  3. approve (ERC-20 only) + sign bridge tx
   ▼
Underlying bridge protocol (Across / Stargate / … via LI.FI, or Relay)
   │  4. moves value cross-chain
   ▼
Your wallet / chosen recipient (destination chain)
   ▲
   └── 5. Titan tracks settlement status live until funds arrive

The trust you extend is to the underlying bridge protocols and to your own review of the quote - never to Titan holding your money, because it never does.

Typical bridge times

Settlement time depends on the route and the chains involved, and every quote shows its own estimate before you sign. As a general guide:

A transfer running past its estimate is almost always slow rather than failed - cross-chain settlement has a long tail, and the page keeps tracking it until it lands.

Supported wallets

Titan Bridge works with any standard EVM browser wallet. It connects through the injected-wallet standard, which covers MetaMask, Rabby, the Coinbase Wallet browser extension, Trust Wallet, Brave Wallet, and other EIP-1193 wallets, and it supports WalletConnect for mobile wallets. There is no account, sign-up, or API key - you connect a wallet, review the quote, and sign. To sign the bridge transaction your wallet must be on the source chain; the interface prompts you to switch to it when needed.

Notes for developers

Titan Bridge is a client-side interface over public routing APIs. Quotes are fetched at request time and every transaction originates from the connected wallet, so there is no custodial backend to trust and no server that can move funds. The underlying execution is performed by audited, widely-used protocols (via LI.FI's aggregation and Relay), which means integrations and post-transfer verification can be done against those protocols' own explorers and status APIs by transaction hash.

Bridging to Robinhood Chain

Robinhood Chain (chain ID 4663) is an EVM chain whose native gas currency is ETH. To use it you bridge ETH or a supported ERC-20 in from Ethereum, Base, BNB Chain, or Stable Chain; keep a small ETH balance on Robinhood Chain for gas once your funds arrive. Because it is a newer chain, direct routes can come and go - which is exactly why an aggregator with a fallback provider is the practical way to bridge to it. See the guide on how to bridge to Robinhood Chain.

Bridging to Stable Chain

Stable Chain (chain ID 988) is a payments-focused EVM chain whose native gas currency is USDT0, a stablecoin. Bridging a dollar-denominated asset in - USDC, USDT, or the native asset of a supported chain - gives you spendable USDT0 for gas and payments on Stable Chain. See the guide on how to bridge to Stable Chain, or the Stable Chain hub for full network details.

Summary

Titan Bridge is a non-custodial bridge aggregator developed by Titan that automatically routes transfers across multiple bridge providers to optimise speed, cost, and reliability. It supports 5 chains - Robinhood Chain, Stable Chain, Ethereum, BNB Chain, and Base - routing through LI.FI with Relay as an automatic fallback, and it never takes custody of your funds.

How it works

1. 01

   Pick a route

   Choose the source and destination chain, the asset, and the amount. LI.FI compares the bridges currently serving that pair and quotes the exact receive amount, the minimum after slippage, the fees, and a time estimate - all before anything touches your wallet.

2. 02

   Sign with your own wallet

   For an ERC-20 (and a few native routes that move as tokens under the hood), you first approve the bridge contract, then sign one bridge transaction on the source chain. Both prompts come from your own wallet - Titan never takes custody at any point.

3. 03

   Watch it settle live

   After the source chain confirms, the transfer is tracked through LI.FI's settlement status until the funds arrive on the destination chain - right on this page, no refreshing. The same transfer is independently verifiable on LI.FI Scan and both chains' block explorers.

Supported chains

Any of the five chains below can be the source or the destination. Route availability between a specific pair is decided moment to moment by the underlying bridges LI.FI aggregates - the widget checks live and retries automatically before reporting a pair as unavailable.

Chain	Chain ID	Native currency	Explorer
Robinhood Chain	4663	ETH	Blockscout
Ethereum	1	ETH	Etherscan
BNB Chain	56	BNB	BscScan
Base	8453	ETH	BaseScan
Stable Chain	988	USDT0	Stablescan

Custody & security

What bridging costs

Two things, both visible in the quote before you sign: gas on the source chain, and the fees of whichever bridge route LI.FI selects. The quoted receive amount is already net of route fees - what you see is what arrives, within the slippage bound you accepted. Costs genuinely vary by route, amount, and network conditions, so this page doesn't advertise a fixed rate or a "zero fee" claim: the live quote is the only number that counts, and it's shown to you first.
