Each Ethereum block becomes eligible once its EIP-1559 burn reaches 1 gwei. Pre-activation targets keep 0-fee discovery; post-activation targets require a raw-fragment capture fee. The first canonical emt-mint captures the block.
Loading wallet…
Enter the block you want to mint. The page will tell you whether this mint needs a capture fee. Historical / pre-activation blocks keep the old calldata; when a fee is required, the page adds it to the preview and signing flow.
data:,{"p":"edmt","op":"emt-mint","tick":"enat","blk":"25985919"}Once the target block is confirmed mintable, send the self-send calldata transaction directly from your wallet. The backend-built transaction includes the fee field when protocol rules require it.

The UI is a convenience. You can always construct and submit the calldata yourself — from a hardware wallet, a script, or a command line. Pre-activation targets may omit fee; post-activation targets use the capture fee shown by the page.
Choose an unminted target block. If it is already inside the fee window, make sure the sender has enough raw fragment balance.
Assemble the exact payload below. Replace «N» with your chosen block number. Historical / pre-activation targets should not pass the new fee field; only add fee when the quote above says it is required.
data:,{"p":"edmt","op":"emt-mint","tick":"enat","blk":"<N>"}Send 0 ETH to your own address with this calldata attached. Once finalized, the indexer reads the transaction and credits the eNAT to you.
A mint is accepted once it is included and remains after finality (~12–15 minutes). Only then does the indexer commit ownership.
The signed tx is in the mempool. Gas price must be high enough to be included within the mint window.
The tx is in a mined block. Ownership is tentative until finality; a re-org could still displace it.
Two epochs passed. Re-org probability approaches zero. The indexer now commits ownership.
Queue multiple blocks and submit in a single transaction bundle.
Pre-sign conditional bids that fire only when a block becomes mintable.
Watch blocks by burn threshold or rarity pattern and alert on match.
Route through a private mempool to avoid front-runners on high-value mints.
