Implementation Reference
- src/swap.ts:1040-1085 (handler)The core handler function that executes the wrapping of EDU to WEDU by depositing into the WETH9 (WEDU) contract.
export async function wrapEDU( privateKey: string, amount: string ): Promise<{ hash: string; from: string; amount: string; success: boolean; }> { try { const provider = blockchain.getProvider(); const wallet = new ethers.Wallet(privateKey, provider); const fromAddress = wallet.address; // Convert EDU amount to wei const amountInWei = ethers.parseEther(amount); // Create WETH9 contract instance const wethAbi = [ 'function deposit() external payable', 'function withdraw(uint256 amount) external', 'function balanceOf(address owner) view returns (uint256)', 'function approve(address spender, uint256 amount) external returns (bool)' ]; const wethContract = new ethers.Contract(CONTRACTS.WETH9, wethAbi, wallet); // Deposit EDU to get WEDU const tx = await wethContract.deposit({ value: amountInWei }); const receipt = await tx.wait(); if (!receipt) { throw new Error('Transaction failed'); } return { hash: tx.hash, from: fromAddress, amount, success: true }; } catch (error) { console.error('Error wrapping EDU to WEDU:', error); throw error; } } - src/index.ts:676-692 (schema)The input schema definition for the 'wrap_edu' tool, specifying parameters privateKey and amount.
