Configuration

Configuring a contract
A definition of all configuration parameters that can change the bridge behavior are available in the xDai Bridge Management API. We describe the steps for changing the daily limit of the Bridge Home contract (0x7301cfa0e1756b71869e93d4e4dca5c7d0eb0aa6, deployed in the xDai chain). 
The instructions use NiftyWallet to invoke contract methods. An example how to use this functionality is available here​
Any tool that can create transactions based on contract source code or the ABI may be used.
These steps can also be used on other parameters of this or another contract:
1.Use the setDailyLimit method from HomeBridgeErcToNative ABI and a new daily limit (in this example the new limit is 50000 xDai coins) to encode the data for the transaction. Example of the data: b20d30a9000000000000000000000000000000000000000000000a968163f0a57b400000.
2.Open NiftyWallet to invoke submitTransaction of the multisig wallet contract (0x0d3726e5a9f37234d6b55216fc971d30f150a60f on the xDai chain). The destination must be 0x7301cfa0e1756b71869e93d4e4dca5c7d0eb0aa6. The data field must be filled with the bytes received on the previous step. 
3.Identify the index of the transaction returned in the Submission event as soon as the transaction from the previous step is included into a block and share it with the other multisig wallet owners.
4.(for the rest of owners) Use NiftyWallet to invoke confirmTransaction of the multisig wallet contract (0x0d3726e5a9f37234d6b55216fc971d30f150a60f). Set the gas limit two times bigger than the gas estimator suggests.
5.Since any modification of the daily limit on one side must be reflected on another side,  as described below, steps 1 - 4 need to be executed on the ETH Mainnet. Use the setExecutionDailyLimit method from ForeignBridgeErcToNative ABI and the same daily limit used in step 1 to encode the data for the transaction. Example of the data: 3dd95d1b000000000000000000000000000000000000000000000a968163f0a57b400000.
6.Use NiftyWallet to invoke submitTransaction of the multisig wallet contract (0xff1a8EDA5eAcdB6aAf729905492bdc6376DBe2dd on the ETH Mainnet). The destination must be 0x4aa42145Aa6Ebf72e164C9bBC74fbD3788045016. The data field must be filled with the bytes received on the previous step. 
7.Identify the index of the transaction returned in the Submission event as soon as the transaction from the previous step is included into a block and share it with the other multisig wallet owners.
8.(for the rest of owners) Use NiftyWallet to invoke confirmTransaction of the multisig wallet contract (0xff1a8EDA5eAcdB6aAf729905492bdc6376DBe2dd). Set the gas limit two times bigger than the gas estimator suggests.
