Stablecoin Issuance on Bitcoin
Issue stablecoins natively on Bitcoin with instant settlement, no bridges, and full programmability. USDT and USDB already live on Spark.
Stablecoin issuance is fragmented across chains that weren't built for it
Ethereum, Tron, and Solana each require separate infrastructure, separate compliance, and separate reserves. Bridge risk means every chain adds systemic failure points. High gas fees make small transactions uneconomical. Most importantly, stablecoins don't exist natively on Bitcoin: the largest, most secure, most liquid network sits empty while issuers fragment liquidity across weaker chains. Financial institutions need a Bitcoin-native option that offers instant settlement, programmable issuance, and access to Bitcoin's trillion-dollar liquidity without wrapped tokens or bridge dependencies.
What we do
Native stablecoin issuance on Bitcoin, no compromises
Instant settlement on Bitcoin
Stablecoins on Spark settle in under a second with finality. No block times, no gas fees, no congestion. Transfers are free within the network: users only pay Bitcoin fees when entering or exiting.
USDT and USDB already live
Tether issued USDT natively on Spark. Brale and Flashnet launched USDB. Both are real, audited stablecoins: no wrapped tokens, no synthetic derivatives, no bridge assumptions. Your stablecoin can join them.
Built on Bitcoin's security model
Spark is anchored to Bitcoin's blockchain via state commitments. Every stablecoin transaction inherits Bitcoin's security guarantees. Unlike separate chains, there's no new consensus layer to trust or attack.
Programmable issuance via SDK
Mint, burn, and manage balances programmatically. No smart contract deployment, no gas fees, no EVM complexity. The Spark SDK gives you full control over issuance, redemptions, and compliance workflows.
Why Spark
Issue stablecoins on Bitcoin in five steps
Register your stablecoin asset
Define your token parameters: ticker, precision, compliance rules. Spark handles the protocol-level registration. No smart contract code, no deployment fees.
Integrate the issuance API
Use the Spark SDK to mint and burn tokens programmatically. Every issuance event is cryptographically signed and anchored to Bitcoin's blockchain.
Users hold stablecoins in self-custodial wallets
Wallets built on Spark hold BTC and stablecoins together. Same keys, same interface, same instant settlement. No separate chain, no separate integration.
Transfers settle instantly with no fees
Stablecoin transfers within Spark are free and final in under a second. Bitcoin's security model ensures every transaction is irreversible and auditable.
Scale with Bitcoin's liquidity
Your stablecoin taps into Bitcoin's trillion-dollar network effect. Cross-chain swaps, Lightning interoperability, and instant on-ramps are built in at the protocol layer.

FAQ
Spark is anchored to Bitcoin, not a separate chain. There's no new consensus layer, no bridge risk, no fragmented liquidity. Transfers settle instantly with no gas fees. Users hold stablecoins in the same wallet as their bitcoin, with the same keys.
USDT (Tether) and USDB (issued by Brale via Flashnet) are both live on Spark today. Both are fully backed, audited, and redeemable: real stablecoins, not synthetic wrappers.
No. Stablecoin issuance on Spark is API-driven, not contract-based. You register your asset, define issuance rules, and call mint/burn functions via the SDK. No Solidity, no gas fees, no EVM complexity.
Spark is a Bitcoin protocol extension. It anchors state commitments to Bitcoin's blockchain, inheriting its security model without creating a new chain. Every transaction is cryptographically tied to Bitcoin.
The Spark SDK supports programmable compliance rules: mint/burn permissions, transfer restrictions, KYC gating, and audit trails. You control who can hold and transact your stablecoin.
