About
AN HOMAGE
TO THE PROTOCOL
21M is a memecoin deployed on the Universal BRC-20 Extended protocol — a Satoshi-faithful evolution of BRC-20 that migrates token logic from witness data to prunable OP_RETURN outputs.

No VCs. No insiders. No premine beyond the deployer's fair share. Just a community tribute to the most elegant token protocol ever built on Bitcoin.

The supply cap mirrors Bitcoin itself: 21,000,000. Not a coincidence.
// OP_RETURN
PRUNABLE BY DESIGN
Token logic lives in compact OP_RETURN outputs — not bloated witness data. Efficient. Sustainable. The way Satoshi intended Bitcoin to scale.
// ACCOUNT MODEL
NO ACCIDENTAL BURNS
Balances are tied to addresses, not UTXOs. You cannot accidentally destroy your tokens by spending the wrong output. Ever.
// ATOMIC TX
MULTI-OP IN ONE TX
Send to multiple recipients in a single Bitcoin transaction. Massive fee savings. The primitive that makes DeFi possible on L1.
// COMMUNITY
NO VC. NO BACKING
The Universal Protocol was built by believers, not investors. 21M carries that same energy — a pure community tribute.
