Genesis mint
Clean mint flow for the s404 Ordinals Genesis collection, connected with Xverse.
Spark s404 – fusion of Bitcoin Ordinals & Spark BTKN tokens!
s404 links a native Bitcoin Ordinals collection with a fixed-supply BTKN token on Spark through public vaults and a verifiable 1:1 mapping.
Why s404
1:1 mapped
Dual-layer standard
Ordinals live on Bitcoin. BTKN lives on Spark. Both are tied with a strict 1:1 mapping and public vaults instead of hidden bridge logic.
Spark side
Instant liquidity
Bridge once, then trade, farm, stake and experiment with your BTKN on Spark – without touching heavy UTXO flows on every interaction.
Fully transparent
Auditable by design
Vault addresses are public. Anyone can verify how many Ordinals and BTKN are locked on each side and validate the 1:1 backing invariant.
Genesis phase
Launch incoming
Follow @Spark_s404 on X and turn on notifications to catch the s404 Genesis mint and bridge rollout.
How it works
1
Mint an NFT from the s404 Ordinals collection directly to your Xverse Ordinals address. It behaves like any other native Bitcoin inscription.
2
Hold, send and trade your s404 Ordinals on Bitcoin marketplaces as usual. It’s a standard inscription until you decide to bridge.
3
Send the Ordinal to the public Bitcoin vault. The bridge detects the deposit and releases the matching BTKN from the Spark vault to your Xverse Spark address.
4
Trade BTKN on Spark, plug it into DeFi, apps and experiments – knowing every token stays fully backed by a locked Ordinal on Bitcoin.
5
Read the full specification, vault addresses and security model in the s404 Docs.
