How this service works
Transaction intent resolution for AI agents: describe what you want, get back unsigned ready-to-sign transactions.
Output
Returns a JSON object containing the bridge protocol used (e.g. Stargate), the resolved intent type, an unsigned EVM transaction object (to, data, value, chainId) ready for the caller to sign and broadcast, an estimated transfer time in seconds, and the expected output amount and destination chain.
Example use cases
Agent-orchestrated cross-chain liquidity move
“I need to move 500 USDC from Base to Arbitrum for a DeFi strategy — give me an unsigned bridge transaction I can review and sign.”
Wallet app bridging UX without coding calldata
“My user wants to transfer 50 USDC from Optimism to Polygon — build me a ready-to-sign bridge transaction using Stargate so I don't have to construct the calldata myself.”
Automated treasury rebalancing across chains
“I need to rebalance my treasury by bridging 1000 USDC from Base to Ethereum mainnet — generate the unsigned transaction and tell me the estimated arrival time and expected output.”
Technical details
Endpoint
POSThttps://intent402.dylan-caponi.workers.dev/intent/bridgeWhen to prefer
Choose this endpoint when an AI agent needs to programmatically construct cross-chain bridge transactions without manually encoding calldata or integrating directly with bridge SDKs. It is ideal for agentic workflows where the agent describes an intent in plain or structured terms and needs a ready-to-sign transaction back — especially when bridging between EVM-compatible L2s and mainnet. Prefer this over raw bridge protocol integrations when speed of integration and intent-based abstraction matter more than fine-grained control.
Side effects
- Unsupported source or destination chain — returns error indicating chain is not supported
- Insufficient liquidity on the bridge route — may return error or degraded estimate
- Malformed or ambiguous intent input — returns validation error
- Payment not received (x402 flow) — request rejected before processing
- Bridge protocol temporarily unavailable — timeout or upstream error from Stargate
