Governance Decisions

The Bridge Governance Board is responsible for enacting updates related to bridge functionality, contract upgrades, and other parameters impacting bridge operations. The following items have been implemented by the board.

Onboarding EURC.e to Gnosis Chain, reset default dailyLimit and executionDailyLimit, remove fees for existing tokens, replace Telepathy validator address​

🗳 Justification:

  1. To comply with Circle’s bridged token standard, we have deployed Bridged EURC on the Gnosis Chain. Unlike the typical bridged token from Omnibridge, Bridged EURC on Gnosis Chain uses the latest version of the FiatToken standard, v2.2. Therefore, registering Bridged EURC on Gnosis Chain’s Omnibridge and setting default values for dailyLimit and executionDailyLimit are necessary to meet the token bridge limit requirements. Setting default dailyLimit and executionDailyLimit will not affect the current bridged token, but only newly bridged token, and it can be reset for individual tokens by calling setDailyLimit and setExecutionDailyLimit through governance process.
    • Bridged EURC on Gnosis Chain (EURC.e): 0x54E4cB2a4Fa0ee46E3d9A98D13Bea119666E09f6
    • new default dailyLimit: 10000000000000000000000000000000000010
    • new default executionDailyLimit: 10000000000000000000000000000000000010
  2. Removing the fee of the following tokens as well as setting default fee to 0, meaning all the future newly bridged token from Omnibridge will be zero fee. BAL, PNK, CRV, CRVUSD, LINK, HOPR, COW, DXD, WSTETH
  3. Increasing the daily and transactions limits for: WETH, WBTC, GNO, USDC, USDT, HOPR
  4. Replacing Telepathy validator address with a new one.

✅ Implemented: Mar 13, 2023

Increase required block confirmation for AMB to 130 blocks, remove Autonolas LP token fee​

🗳 Justification: To increase the participation of the Telepathy light client on the AMB, we increase the required block confirmations from 100 blocks (~20 mins) to 130 blocks (~26 mins). This will ensure that the majority of the txs can be signed by Telepathy. End users should expect 6 more minutes delay. Besides, as requested from Autonolas team, we remove the Autonolas LP token fee on ETH↔GC Omnibridge, from previously 0.01% to 0.

✅ Implemented: Dec 18, 2023

Remove OLAS token fee from ETH-GC Omnibridge​

🗳 Justification: As requested from Autonolas team, we removed OLAS token fee on ETH↔GC Omnibridge, from previously 0.01% to 0.
OLAS on Ethereum: https://etherscan.io/address/0x0001a500a6b18995b03f44bb040a5ffc28e45cb0
Bridged OLAS token on Gnosis: https://gnosisscan.io/address/0xce11e14225575945b8e6dc0d4f2dd4c570f79d9f

✅ Implemented: Nov 9, 2023

Savings xDAI launch - Initiate sDAI interest bridging and increase xDAI bridge limits.​

🗳 Justification: This is a follow-up on the previous proposal. After the successful upgrade of the xDAI bridge to deploy reserves on the sDAI vault, we launched the Savings xDAI vault on Gnosis chain which will distribute the interest earned on mainnet to holders of the sDAI token on Gnosis chain. We set interest receiver to the interest receiver contract on Gnosis Chain.

We increased the limits for incoming xDAI transactions to Gnosis chain as we are anticipating higher volumes due this launch. Previous value: 10 million. New value: 15 million.

✅ Implemented: Oct 5, 2023

Upgrade xDAI bridge to support investing in sDAI vault.​

🗳 Justification: We upgrade xDAI bridge to new implementation version in order to support investing DAI from the bridge contract into sDAI vault from Spark Protocol. This upgrade only implements changes on Ethereum, and the next phase will be on Gnosis Chain. The implementation contract is audited by Omega and ChainSafe. For more details, please refer to docs

We call the method upgradeTo() on the xDAI bridge proxy contract (0x4aa42145aa6ebf72e164c9bbc74fbd3788045016) with parameters: version 8 and impl. 0x166124b75c798cedf1b43655e9b5284ebd5203db.

We call the initializeInterest() with the following parameters.

- DAI: 0x6b175474e89094c44da98b954eedeac495271d0f
- minCashThreshold: 1000000000000000000000000 (1,000,000 DAI)
- minInterestPaid: 1000000000000000000000 (1,000 DAI)
- interestReceiver: 0x0000000000000000000000000000000000000000

We also call investDAI() to invest the DAI into MakerDSR. 25m DAI have been deposited into sDAI vault earning interest.

refillBridge() will be called periodically (once per day at the moment) by the Karpatkey team to ensure that there is enough DAI for withdrawal on Ethereum.

✅ Implemented: Sept 20, 2023

Add Telepathy Validator in the AMB​

🗳 Justification: Adding the Telepathy validator in the AMB as the 8th validator.

Telepathy is a light client based validator developed by SuccinctLabs. Main goal is to increase security of the bridge by adding a validator that is not based on trusted off-chain agents but on verifying the transactions based on the Ethereum consensus layer. We are also increasing the minimum required block confirmations to 100 blocks so that the Telepathy validator has enough time to participate in the transaction affirmation process.
This initiative is part of this proposal that started a year ago: https://forum.gnosis.io/t/gip-57-should-gnosis-dao-support-research-of-a-zksnark-enabled-light-client-and-bridge/5421
More details on the design: https://hackmd.io/@wdyZgTm3RrOsm-rhXDXEHA/BJ_7ExKgn

✅ Implemented: Jul 3, 2023

Remove two governor wallets, add three new governor wallets and remove HAUS token fee.​

🗳 Justification: We removed two inactive governor wallets from ex-xDAI team and add three new governor wallets: Succinct Labs, Agave, Gnosis Bridge team. Additionally, we increased governance Safe wallet’s threshold from 7 to 8, resulting in 8-of-16 requirement to pass a proposal, strengthening the resilience of the bridge governance. Besides, as requested from DAOHAUS team, we removed HAUS token fee, making it a complete fee-less operation to bridge HAUS token between ETH and Gnosis Chain.

✅ Implemented: Jun 12, 2023

Upgrade BNB-GC Omnibridge mediator to stop accepting any new token locks and mints​

🗳 Justification: As part of the longer term plan to decommission the BNB-GC Omnibridge (more info https://forum.gnosis.io/t/bridge-to-binance-update/6624), we want to stop any new token locks and mints from either BNB chain or Gnosis Chain.

✅ Implemented: April 4, 2023

Safe contract updates, two new governor wallets and Gateway validator addition.​

🗳 Justification: We executed a regular/routine update for all Safe contracts. Additionally, we added one more validator (7 in total), strengthening even further the resilience of the bridges. Finally, we replaced two recently inactive wallets with new participants that will participate in the governance more actively.

✅ Implemented: March 20, 2023

Adjust limits on ETH-GC OmniBridge for WETH, WBTC, GNO, CLNY, DXD, HOPR, HAUS​
