deposit()
deposit(
walletAddress,value):object
Deposit tokens(e.g. WETH) in exchange for pufETH. This doesn't make the
transaction but returns two methods namely transact and
estimate.
Parameters
| Parameter | Type | Description |
|---|---|---|
walletAddress | `0x${string}` | Wallet address to get the tokens from. |
value | bigint | Value of tokens to deposit. |
Returns
object
transact: (value: bigint) => Promise<Address> -
estimate: () => Promise<bigint> - Gas estimate of the
transaction.
estimate()
estimate: () =>
Promise<bigint>
Returns
Promise<bigint>
transact()
transact: () =>
Promise<`0x${string}`>
Returns
Promise<`0x${string}`>

depositETH()
depositETH(
walletAddress):object
Deposit ETH in exchange for pufETH. This doesn't make the
transaction but returns two methods namely transact and
estimate.
Parameters
| Parameter | Type | Description |
|---|---|---|
walletAddress | `0x${string}` | Wallet address to get the ETH from. |
Returns
object
transact: (value: bigint) => Promise<Address> - Used to
make the transaction with the given value.
estimate: () => Promise<bigint> - Gas estimate of the
transaction.
estimate()
estimate: () =>
Promise<bigint>
Returns
Promise<bigint>

Returns
object
The viem contract.

getExitFeeBasisPoints()
getExitFeeBasisPoints():
Promise<bigint>
Returns how many basis points of a fee there are when exiting. For example, a 1% fee would mean 1% of the user's requested pufETH is burned (which increases the value for all pufETH holders) before the ETH is redeemed. i.e., you get 1% less ETH back.
Returns
Promise<bigint>
Basis points of the exit fee.
