A token platform that runs on top of blockchains you already trust, rather than asking you to move to a new one. Tokens, an exchange, smart contracts and cross-chain swaps, all living directly on Bitcoin, Litecoin and Dogecoin.
XChain embeds a complete protocol inside ordinary blockchain transactions. Every token it creates inherits the host chain's proof-of-work security wholesale, because the chain underneath is never modified and nothing is ever moved somewhere less safe to make it work.
For a decade, doing more than payments on a blockchain has meant leaving the secure chains behind: moving value onto bridges, sidechains, and new networks with their own validators and their own trust assumptions. That is also where the money gets stolen. Cross-chain bridges are among the most exploited constructs in crypto, with billions lost.
The largest and most secure chains were never extended to do this safely. XChain adds the capabilities people actually want on top of those chains, inheriting their security instead of rebuilding it on something weaker.
XChain is a metalayer: a protocol that runs above an unmodified base blockchain, using ordinary transactions to carry its data. Software running the protocol reads those transactions and derives its own state (balances, order books, contract storage) by a fixed set of rules that anyone can replay and check independently.
The whole stack is expressed as 36 standard ACTIONs: issue and manage tokens, transfer and airdrop, trade on a native on-chain exchange, swap across chains, deploy and call smart contracts, publish encrypted token-gated content, stake, and store data. None of it is Bitcoin-specific, and adding another Bitcoin-compatible chain is a configuration change rather than a rebuild.
What makes it different
Most platforms make the contract engine be the protocol, so a single contract bug can drain funds or mint from nothing. Here a contract cannot touch the ledger directly. It emits the same validated operations a user would, through the same audited handlers, so a bug can fail without breaking the protocol.
A contract can pose a question to an HTTPS endpoint or an approved AI model. Validators answer independently, agree, and write the verified result on-chain, so the outcome is reproducible by anyone replaying the chain. The answer arrives through a callback, not instantly.
Nothing is wrapped and nothing is locked, so there is no bridge to attack. Cross-chain swaps are coordinated, never custodied, by a staked validator network: tokens stay on their home chains and only ownership changes. Scoped to the chains XChain runs on.
Built, not promised
XChain is live in production on Bitcoin, Litecoin and Dogecoin, with public explorer, encoder and validator-hub services, and cross-chain settlement working end to end.
It is open source under the AGPL-3.0, with a commercial license available for organizations that need to keep modifications private. It is built and maintained by Dankest, LLC, whose co-founders were previously maintainers of Counterparty, the long-running token metalayer on Bitcoin.
On fees, one thing is worth stating plainly because it is the first question most people ask: the platform has a gas token, XCHAIN, and protocol fees are priced in it, but you pay them in the chain's own coin. On Litecoin and Dogecoin that is the only way fees are paid; on Bitcoin you may use an XCHAIN balance instead if you hold one. You never have to acquire XCHAIN to use the platform.
