Wallet Contracts

ETH forwarder with configurable destination. Forwards incoming Ether to a parent address set at deployment, with an owner-only flush() method.

Minimal ETH forwarder. Hardcodes a destination address at deployment and unconditionally forwards all incoming Ether to it.

Exchange deposit wallet that collects ERC20 tokens via collect(tokenAddress, recipient, amount) and ETH via a payable fallback function.

User withdrawal account. Holds ETH and ERC20 tokens on behalf of a user and allows owner-authorized withdrawals to a registered user address.

ETH forwarder with administrative controls. Forwards incoming Ether to a parent address and supports flushTokens(ERC20) and a kill() self-destruct.

BitGo WalletSimple multisig wallet. Requires two-of-three key signatures for sendMultiSig ETH transfers and sendMultiSigToken ERC20 transfers.

ERC223-compatible deposit wallet. Accepts token transfers via tokenFallback and sweeps held ERC20 tokens to a configured owner address.

Payment forwarding contract from BitGo's exchange infrastructure. Receives ETH and forwards it to a parent address for deposit address management.

Proxy wallet pattern used by exchanges and custodians. Each instance delegates to a shared implementation, deployed millions of times by factory contracts.
