Platform Wallet

Every Stagenet includes a Platform Wallet — a built-in account for sending transactions without signing or worrying about token balances and approvals.

It has special behaviour on your Stagenet:

You can send transactions from it in the app without signing.
It has unlimited native token balance for gas.
It reads as having the maximum balance of every ERC20 token.
It reads as having maximum ERC20 allowance for every spender.

Its details:

Sending transactions

Anywhere you can send a transaction in the app — such as a contract dashboard’s interact panel — you can choose between your browser wallet and the Platform Wallet (instant + gasless). Choosing the Platform Wallet sends the transaction immediately with no signing step.

The Platform Wallet is also returned by eth_accounts and used for eth_sendTransaction requests, so scripts and local tooling can use it too.

ERC20 behaviour

token.balanceOf(platformWallet) always returns type(uint256).max.
token.allowance(platformWallet, spender) always returns type(uint256).max, for any spender.
