Sui Bridge is the native bridge for the Sui network, integrated into its core architecture. It enables asset movement between Sui and other blockchains. Sui validators operate and govern Sui Bridge. Bridge transfers and other actions require validator signatures with a threshold of voting power. Common mistakes include assuming any token can be bridged (only specific supported assets are available), misunderstanding the global limiter constraints, and not accounting for finality requirements on both chains.

Sui Bridge 是 Sui 网络的原生跨链桥，已集成到其核心架构中。它支持资产在 Sui 与其他区块链之间转移。Sui Validator 负责运营和治理 Sui Bridge。桥接转账及其他操作需要获得达到投票权阈值的 Validator 签名。常见错误包括：误以为任何代币都可跨桥（实际上只有特定的支持资产可用）、误解 global limiter 的限制，以及未考虑两条链上的 finality 要求。

Skill 内容

Key concepts

核心概念

  • Native bridge. Sui Bridge is the native bridge for the Sui network, integrated into core architecture. It is not a third-party bridge. Bridge tokens at bridge.sui.io.
  • Validator-operated. Sui validators (the same entities securing the network) operate and govern Sui Bridge. Bridge transfers and other actions require validator signatures with a threshold of voting power.
  • Governance. Governance occurs through validator voting. Actions require a threshold of validator voting power.
  • Supported assets. The bridge supports a specific set of assets: WBTC, LBTC, ETH, WETH, and USDT.
  • Global limiter. The bridge constrains total asset value leaving the bridge within 24 hours. Current limits are $16 million (Ethereum to Sui) and $7 million (Sui to Ethereum) daily, with ETH priced at $2,600 for limit calculations.
  • Open source and audited. The bridge source code is open source (Move, Solidity, bridged ETH, bridge node, and bridge indexer implementations). Third-party security audits have been conducted by OtterSec and Zellic.
  • 原生跨链桥。 Sui Bridge 是 Sui 网络的原生跨链桥，已集成到核心架构中。它不是第三方桥。请在 bridge.sui.io 进行代币跨链。
  • 由 Validator 运营。 Sui Validator（与保护网络安全的主体相同）负责运营和治理 Sui Bridge。桥接转账及其他操作需要获得达到投票权阈值的 Validator 签名。
  • Governance。 Governance 通过 Validator 投票进行。各项操作都需要 Validator 投票权达到规定阈值。
  • 支持的资产。 该桥支持一组特定的资产：WBTC、LBTC、ETH、WETH 和 USDT。
  • Global limiter。 该桥会限制 24 小时内离开桥接系统的资产总价值。当前每日限额为 1,600 万美元（Ethereum → Sui）和 700 万美元（Sui → Ethereum），计算限额时 ETH 按 2,600 美元计价。
  • 开源且经过审计。 桥接源代码是开源的，包括 Move、Solidity、bridged ETH、bridge node 和 bridge indexer 实现。OtterSec 和 Zellic 已开展第三方安全审计。

Rules

规则

  1. Always specify the direction when discussing limits. The global limiter has different limits for Ethereum-to-Sui ($16 million) vs Sui-to-Ethereum ($7 million).
  2. Always note finality requirements. Ethereum-to-Sui requires configurable Ethereum block confirmations before minting. Sui-to-Ethereum requires Sui transaction finality before releasing tokens. Do not credit the user until the bridge transfer is fully confirmed on the destination chain.
  3. Only reference supported assets. The bridge supports WBTC, LBTC, ETH, WETH, and USDT. Do not suggest other tokens can be bridged.
  1. 讨论限额时始终注明方向。 global limiter 对 Ethereum → Sui（1,600 万美元）和 Sui → Ethereum（700 万美元）设置了不同的限额。
  2. 始终说明 finality 要求。 Ethereum → Sui 在铸造前需要经过可配置的 Ethereum 区块确认。Sui → Ethereum 在释放代币前需要 Sui 交易达到 finality。在桥接转账于目标链上完全确认之前，不要为用户入账。
  3. 仅引用支持的资产。 Sui Bridge 支持 WBTC、LBTC、ETH、WETH 和 USDT。不要暗示其他代币也可以跨链。

Common mistakes

常见错误

  • Assuming any ERC-20 token can be bridged. Only the specifically supported assets (WBTC, LBTC, ETH, WETH, USDT) are available on Sui Bridge.
  • Ignoring the global limiter. Large transfers may be constrained by the 24-hour rolling limit.
  • Not accounting for finality delays. Transfers are not instant. Ethereum-to-Sui requires Ethereum block confirmations; Sui-to-Ethereum requires Sui transaction finality.
  • Confusing transfer precision. ETH/WETH transfers use 8-decimal precision on the bridge.
  • 误以为任何 ERC-20 代币都可以跨链。 Sui Bridge 仅提供特定的支持资产（WBTC、LBTC、ETH、WETH、USDT）。
  • 忽略 global limiter。 大额转账可能受到 24 小时滚动限额的约束。
  • 未考虑 finality 延迟。 转账并非即时完成。Ethereum → Sui 需要 Ethereum 区块确认；Sui → Ethereum 需要 Sui 交易达到 finality。
  • 混淆转账精度。 ETH/WETH 转账在桥上使用 8 位小数精度。
