Wallet EVM 7702 Gasless Overview

The @tetherto/wdk-wallet-evm-7702-gasless module manages EVM externally owned accounts that use EIP-7702 delegation and ERC-4337 UserOperations for gasless transaction flows.

Use this module when your application needs the user to keep an EOA address while submitting transactions through a bundler and paymaster. The module handles EIP-7702 authorization, UserOperation construction, UserOperation signing, paymaster data, and receipt lookup behind the WDK wallet account interface.

What It Provides

• EOA-based EIP-7702 accounts: getAddress() returns the EOA address. The account delegates execution to the configured delegationAddress when needed.
• Sponsored transactions: Set isSponsored: true to use a sponsorship policy. Quotes return a zero fee in sponsored mode.
• Paymaster-token transactions: Configure paymasterToken to pay UserOperation costs in an ERC-20 token.
• Provider failover: Pass one provider or an ordered list of RPC URLs / EIP-1193 providers. Provider arrays support retries.
• UserOperation receipts: Resolve a UserOperation hash through getUserOperationReceipt() or map it to an EVM transaction receipt with getTransactionReceipt().
• Read-only and signing accounts: Use WalletAccountReadOnlyEvm7702Gasless for balances, quotes, receipts, allowances, and verification. Use WalletAccountEvm7702Gasless when you need signing and sending.
• EVM signing support: Sign plain messages and EIP-712 typed data through the wrapped EVM account.

Requirements

This module depends on EVM infrastructure that supports both EIP-7702 account delegation and ERC-4337 UserOperations. You need:

• an RPC provider for a chain where the EIP-7702 flow is available;
• an ERC-4337 bundler URL;
• a paymaster endpoint, either the same as bundlerUrl or a separate paymasterUrl;
• a trusted smart-account implementation address for delegationAddress;
• either a sponsorship policy or an ERC-20 paymaster token configuration.
