Cross-Chain Intent Solver Bid Tool

WHAT IT DOES

This tool enables DeFi solvers and service providers to submit and manage bids for cross-chain intents. In an intent-based architecture, users express their desired outcome (an "intent") and solvers compete to fulfill it by submitting bids. The solver who offers the best terms typically wins the right to execute the intent and earn the associated reward. It connects to your wallet and reads the intent contract address, intent ID, intent parameters, solver requirements, bid amount, solver fee, competition status, bid history, and timestamps. The tool signs and submits transactions to submit solver bids, update bid amounts, withdraw bids, record bid metadata, and emit bid events.

HOW TO USE

1. Connect your wallet using the wallet bridge (supports MetaMask, WalletConnect, and other EVM-compatible wallets).

2. Select the target network that matches your intent contract deployment.

3. Enter the intent contract address and the intent ID, then click "load contract" to initialize the connection.

4. Click "fetch intent" to retrieve the intent parameters, competition status, and current bid history.

5. Review the intent parameters to understand what you are bidding on and the competition status to see how many other solvers are bidding.

6. Enter your bid amount (in native token) and your solver fee (also in native token) — the total you commit to the bid is the sum of both.

7. Optionally add solver requirements as JSON (e.g., minimum stake or reputation score) to specify your capabilities.

8. Click "calculate bid" to see the total bid amount and preview the commitment.

9. Click "validate bid" to verify that the intent is open for bidding and your wallet has sufficient balance.

10. Click "submit bid" to sign and submit the transaction that places your bid on the intent.

11. Click "withdraw bid" to remove your bid from the competition if you change your mind.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to interact with any EVM-compatible intent contract that implements a standard interface (getIntent(uint256) view, getCompetition(uint256) view, submitBid(uint256, uint256, uint256, bytes) external payable, withdrawBid(uint256) external, getBidHistory(uint256) view). The submitBid function accepts the intent ID, bid amount, solver fee, and solver requirements as parameters, and requires the solver to send the total bid amount (bid + fee) as value. The contract tracks all bids for each intent, maintaining a mapping of bidder addresses to their bid amounts and a history of all bids. The getCompetition view returns the number of bids, total bid amount, and deadline for the competition, allowing solvers to assess competition levels. When a bid is withdrawn, the contract refunds the full bid amount to the solver. Transaction handling follows EIP-1559 gas price calculations using receipt.effectiveGasPrice for accurate cost reporting. Bid metadata is recorded both in the contract's history and locally for the user's reference.

WHAT IT CANNOT SEE

This tool operates purely on-chain and cannot verify solver capability — it does not check whether the solver actually has the infrastructure, capital, or expertise to fulfill the intent. It cannot ensure intent fulfillment — the tool cannot guarantee that the solver will successfully execute the intent if selected. It cannot detect malicious intents — the tool cannot identify intents that are designed to trap solvers or execute malicious transactions. It cannot guarantee execution — the solver may be selected but fail to fulfill the intent due to technical issues, market conditions, or other factors. The tool also cannot verify that the solver can meet the intent requirements — all capability assertions are self-reported through the requirements field and are not validated on-chain.

PLEASE NOTE

This tool works exclusively with EVM-compatible blockchain networks (Ethereum, Polygon, Arbitrum, Optimism, Base, etc.). It requires the intent contract to implement the interface described above. All transactions incur gas fees paid by the connected wallet, in addition to the bid amount. The tool maintains no persistent storage — all state is refreshed from the blockchain on each session. Submitting a bid is a financial commitment — ensure you can actually fulfill the intent before bidding. Bids are typically refundable if you withdraw before the competition ends, but gas costs are not refunded. Always test on a testnet first and verify that you can meet the intent requirements before bidding on production intents.
