deposit(amount)

Mint ctAssets by consuming the underlying token previously approved to the vault. Before calling deposit(amount), the vault must be approved to spend the underlying token.

Signature​

await vault.deposit(amount: bigint): Promise<Tx>

Parameters​

  • amount: underlying amount, in underlying base units (bigint).

Returns​

  • Tx: transaction object. Call await tx.wait() to confirm.

Example​

// Prerequisite: the vault was created with a signer:
// const vault = getVault(version, vaultAddress, chainId, provider, signer)

const vaultAddr = vault.getAddress();

// Approve 1.0 underlying (SDK helper produces a BigInt in underlying units)
const amount = await vault.toUnderlyingBigInt("1.0");

// 1) Approve underlying to the vault
const erc20 = await vault.getUnderlyingErc20();
const approveTx = await erc20.approve(vaultAddr, amount);
await approveTx.wait();

// (Optional) Preview how many shares you will mint
const preview = await vault.previewConversion(amount);
// console.log("Expected shares:", await vault.applyDecimals(preview.vaultTokensReceivingRaw));

// 2) Deposit 1.0 underlying
const depositTx = await vault.deposit(amount);
const receipt = await depositTx.wait();
console.log("Deposit confirmed in block", receipt.blockNumber);
