Ronin Bridge
Overview
Ronin Bridge is an app for transferring tokens between the Ethereum chain and Ronin. It's a multi-signature bridge, which means that multiple bridge operators must approve a transaction before it can be executed. Multi-sig improves the security and trustworthiness of cross-chain transactions, and prevents any single party from acting maliciously or making unauthorized changes to the transaction.

Withdrawal tier limits
Withdrawing funds from Ronin Bridge involves a tiered system based on the transaction value. The following table outlines the default daily limit per token for each tier:
| AXS | WETH | SLP | USDC | AGG | |
|---|---|---|---|---|---|
| Daily limit per token | Capped at 500,000 | Capped at 4,500 | Capped at 2,000,000,000 | Capped at 2,500,000 | Capped at 500,000,000 |
| Tier 1 | < 100,000 | < 1,000 | < 300,000,000 | < 1,000,000 | < 200,000,000 |
| Tier 2 | ≥ 100,000 | ≥ 1,000 | ≥ 300,000,000 | ≥ 1,000,000 | ≥ 200,000,000 |
| Tier 3* | ≥ 400,000 | ≥ 4,000 | ≥ 1,500,000,000 | ≥ 2,000,000 | ≥ 800,000,000 |
*Tier 3 transactions aren't counted toward the daily limit per token, because they require human review.
For Tier 1 transactions, 70% of validators need to approve automatically. Tier 2 requires 90% automated approval. Tier 3 requires both 90% automated approval and a manual review with a fee of around 0.001% of the transaction value.
