Syscoin Bridge

SYSCOIN BRIDGE

Move SYS between Syscoin UTXO and Syscoin NEVM.

Connect wallets

Pali Wallet

MetaMask

HOW DOES IT WORK?

Move SYS between Syscoin UTXO and Syscoin NEVM using cryptographic proofs.

A proof-based bridge with no custodian.

Burn or freeze assets on the source chain

The source transaction removes the bridged amount from use on one chain and produces the data needed to prove that event.

Mint the corresponding amount on the destination chain

After the bridge validates the source-chain proof, it mints the corresponding 1:1 representation on the destination chain.

FAQ

What is Syscoin?

Syscoin is a dual-chain Layer 1 with a Bitcoin-compatible UTXO chain and an EVM-compatible NEVM chain. The chains operate in parallel and use SYS as the native asset.

What is an SPT?

A Syscoin Platform Token (SPT) is a token issued on the Syscoin UTXO chain through its native asset protocol.

What is SYSX?

SYSX is the UTXO-side bridge representation used when moving SYS between Syscoin UTXO and Syscoin NEVM. The bridge converts between SYS and SYSX at a 1:1 ratio during the transfer flow.

How does the SYS bridge work?

The route is Syscoin UTXO SYS ↔ UTXO SYSX ↔ Syscoin NEVM SYS. Each transfer burns or freezes the source representation, verifies the resulting proof, and mints the corresponding amount on the destination chain.

How long does a transfer take?

Syscoin targets a 2.5-minute block time. Some bridge steps wait for block inclusion or confirmation, so completion time varies with network conditions.

Does Syscoin NEVM run on Ethereum?

No. Syscoin NEVM is Syscoin's EVM-compatible chain. It supports familiar Ethereum tools and wallets when they are configured for the Syscoin network.

Which assets does this bridge support?

This interface supports moving SYS between Syscoin UTXO and Syscoin NEVM through SYSX. Other SPT or ERC-20 assets require a dedicated integration and are not available in this interface.

Which wallets can I use?

Use Pali Wallet for the Syscoin UTXO side. Use MetaMask or a supported Pali Wallet configuration for Syscoin NEVM. Hardware wallets are not supported by this app.

Does the bridge preserve the represented SYS supply?

Yes. The source amount is burned or frozen before the corresponding destination amount is minted, maintaining 1:1 accounting across the supported representations.

Does the bridge use a custodian?

No third party takes custody of a transfer. Users authorize source-chain transactions, and protocol proofs authorize the destination-chain result. Smart-contract, software, network, and wallet risks still apply.

Do I need SYS for transaction fees?

Bridge transactions may require SYS for UTXO transaction fees or NEVM gas. If the app reports an insufficient balance, add SYS to the indicated wallet. Fees vary with network conditions.

Why move SYS between UTXO and NEVM?

Syscoin UTXO provides Bitcoin-style asset transactions, while Syscoin NEVM supports EVM applications and smart contracts. The bridge lets you choose the environment that fits your use case.

Where can I get support?

Open a ticket in Syscoin's official Discord server at discord.gg/syscoin. Request support for an incomplete transfer within 75 days of starting it.
