XChain Platform — Supported Blockchains

The XChain Platform is designed to run on any number of blockchains. Adding support for a new blockchain requires only a coin-specific configuration file defining fee schedules, special addresses, and network parameters — the protocol specification, indexer logic, action handlers, and all tooling remain unchanged. The architecture scales horizontally: each blockchain runs its own independent pipeline (decoder, indexer, explorer, UTXO tracker) with its own databases, while a shared hub coordinates cross-chain operations.

Currently Supported

Chain	Networks	Coin Node	Native Ticker	Status
Bitcoin	mainnet, testnet, regtest	`bitcoind`	`BTC`	Active
Litecoin	mainnet, testnet, regtest	`litecoind`	`LTC`	Active
Dogecoin	mainnet, testnet, regtest	`dogecoind`	`DOGE`	Active

Each chain supports three network types:

Network	Purpose
Mainnet	Production network — real value, permanent transactions
Testnet	Public test network — free test coins, mirrors mainnet behavior
Regtest	Local regression testing network — instant block generation, fully controlled environment

Chain-Specific Differences

The same protocol specification applies across all chains. Chain-specific differences are limited to:

Fee amounts — Issuance fees and DEX listing fees are configured independently per chain
Special addresses — Burn, gas, and donation addresses are unique per chain and per network
Block timing — Each chain has different block intervals and confirmation characteristics
Address formats — Each chain uses its own address encoding (e.g., 1... / bc1... for Bitcoin, L... / ltc1... for Litecoin, D... for Dogecoin)
Transaction parsing — Litecoin requires stripping the HogEx flag; Dogecoin requires stripping AuxPoW headers before parsing with bitcoinjs-lib

Each chain and network combination runs its own independent set of services with its own databases. Tokens on Bitcoin are separate from tokens on Litecoin — they share the same protocol rules but maintain independent state. Cross-chain interaction is possible through the SWAP action coordinated by the hub.

Adding New Blockchains

Any Bitcoin-compatible blockchain can be added to the XChain Platform. The requirements are:

The blockchain must support a Bitcoin-compatible JSON-RPC interface (standard getblock, getrawtransaction, etc.)
Transactions must be parseable by bitcoinjs-lib (with optional pre-processing for chain-specific quirks)
A coin-specific configuration file must be created defining fee schedules and special addresses per network

Regtest and Private Blockchains

The regtest (regression test) network type is a locally-controlled blockchain environment where blocks are generated on demand rather than through proof-of-work mining. Regtest is essential for development and testing, but its capabilities extend far beyond that.

Development and Testing

In regtest mode, the xchain-regtest-miner service monitors the mempool and mines blocks automatically — typically waiting a few seconds to batch transactions before generating a block. This enables:

Instant confirmation — No waiting for miners; transactions are confirmed in seconds
Free transactions — Regtest coins have no real value, so developers can test freely
Reproducible environments — Start from block 0 with a known state every time
Automated testing — The xchain-e2e-test suite runs entirely on regtest, creating wallets, broadcasting actions, and verifying state programmatically

Custom Networks for Private Deployments

Regtest networks are fully isolated — they have no connection to any public blockchain. This makes them ideal for creating custom private blockchain deployments where an organization controls the entire network:

Private token platforms — Companies can run XChain on a private regtest network to issue and manage tokens in a controlled environment with no public blockchain exposure
Internal asset tracking — Track ownership, transfers, and audit trails for internal assets using the full XChain token lifecycle (ISSUE, SEND, MINT, DESTROY, SWEEP)
Controlled trading — Use the built-in DEX (ORDER, DISPENSER) for internal markets with configurable fee structures
Data notarization — Use BROADCAST and FILE actions to create tamper-proof records on a private chain
Custom governance — Allow/block lists, minting windows, and lockable parameters provide fine-grained control over token behavior

A private deployment runs the same software stack as a public deployment — the only difference is that the coin node runs in regtest mode and the network is not connected to any public peers.
