Mint a block.
Each Ethereum block becomes eligible once its EIP-1559 burn reaches 1 gwei. The first transaction that submits a canonical emt-mint calldata captures the block. One block, one eNAT — nothing else counts.
The floor.
The heaviest mintable blocks, ranked by EIP-1559 burn. The first valid signature on mainnet captures the block — every other transaction is rejected.
Refreshes as captures land. No queue, no waitlist, no admin to ask.

Demo data.This is an interactive preview wired to a deterministic mock. Real captures appear once the indexer and wallet are connected; the calldata, ordering, and finality model are protocol-correct.

Your wallet sends a transaction whose data field contains the calldata below. The ETH cost is only the Ethereum gas fee — nothing is paid to any team or contract.
You may copy this and submit from any wallet. The first valid submission confirmed on mainnet captures the block.
data:,{"p":"edmt","op":"emt-mint","tick":"enat","blk":"24836710"}Skip the UI. Sign the calldata.
The UI is a convenience. You can always construct and submit the calldata yourself — from a hardware wallet, a script, or a command line. The protocol layer does not distinguish them.
- 01
Pick a block
Choose a historical or current block that has not been minted yet. The block number N is the only parameter unique to you.
- 02
Compose calldata
Assemble the exact payload below. Replace «N» with your chosen block number. No whitespace, no extra fields — the indexer rejects deviations.
data:,{"p":"edmt","op":"emt-mint","tick":"enat","blk":"<N>"} - 03
Self-transfer
Send 0 ETH to your own address with this calldata attached. Once finalized, the indexer reads the transaction and credits the eNAT to you.
How finality works.
A mint is accepted once it is included and remains after finality (~12–15 minutes). Only then does the indexer commit ownership.
- 01
Pending
The signed tx is in the mempool. Gas price must be high enough to be included within the mint window.
- 02
Included
The tx is in a mined block. Ownership is tentative until finality; a re-org could still displace it.
- 03
Finalized
Two epochs passed. Re-org probability approaches zero. The indexer now commits ownership.
Pro minting.
Batch mint
Queue multiple blocks and submit in a single transaction bundle.
Auto-bid window
Pre-sign conditional bids that fire only when a block becomes mintable.
Monitor
Watch blocks by burn threshold or rarity pattern and alert on match.
Private relay
Route through a private mempool to avoid front-runners on high-value mints.
