What became possible

Why does sending ETH to someone else still cost 21,000 gas, while sending it to yourself costs 12,000?

EIP-2780 replaces the flat intrinsic charge with named pieces. A value transfer to an existing account is still 12,000 for the sender, plus 3,000 to touch the recipient, plus 6,000 to move the value. A self-send keeps only the 12,000. A call that moves no value is 15,000. Fusaka charges 21,000 for all three.

The MCP server runs your transaction. It does not ship demo transactions.

Job

Amsterdam

On Glamsterdam, what intrinsic gas does a plain 1 wei transfer to an existing account use?

Look forgasUsed of 21,000

Agent will likely call run_transaction

Lesson

Amsterdam

On Glamsterdam, compare a self-transfer with a zero-value call to an existing account — how much gas does each use?

Look for12,000 for the self-send and 15,000 for the zero-value call

Agent will likely call run_transaction

Check

Amsterdam

On Amsterdam, a transfer uses gasLimit 21000 but also creates a new account — is it rejected or included and reverted?

Agent will likely call run_transaction

What the server does

1. 1

   Discover support

   Confirm the 2780 row; tools is run_transaction.

2. 2

   Run transaction

   Same transfer on fusaka then glamsterdam; read gasUsed.

Prefund the recipient when it should already exist, so the run does not also create an account. A self-send uses the same address for sender and recipient.

Fork caveat

Run the same transaction twice — fusaka (baseline), then glamsterdam (preview). A value transfer to an existing account stays 21,000 on both, with no state gas. A self-send drops to 12,000 only on Glamsterdam. A zero-value call drops to 15,000 only on Glamsterdam. The piece names are not separate result fields; the total is gasUsed.

Creating a new account still adds state gas. That charge is EIP-8037, not this split.
