Eip7702Context class

Holds the shared configuration and network environment used by all EIP-7702 builders, transaction utilities, and signing workflows.

An Eip7702Context encapsulates:

• delegateAddress — the implementation contract that externally owned accounts (EOAs) will delegate to via EIP-7702.
• web3Client — the active Web3Client instance for RPC access.
• chainId — the connected network’s chain ID, cached for reuse.
• transformer - useful for overriding the estimated gas

This context is typically supplied to builders such as AuthorizationBuilder and SetCodeTxBuilder via Eip7702Base, and ensures that all operations share consistent network and configuration state.

Creating a context

Most applications should use the create7702Context factory, which creates a Web3Client internally:

final ctx = create7702Context(
  rpcUrl: 'https://rpc.example.com',
  delegateAddress: '0x1234...',
);
