Change the OSM price source

To build a proposal to change the OSM price source call the propose() function with the following params:

  • targets: [GOV_ACTIONS_CONTRACT_ADDRESS]
  • values: [] (empty)
  • signatures: [] (empty)
  • calldatas: ["0x5622b051000000000000000000000000d4a0e3ec2a937e7cca4a192756a8439a8bf4ba910000000000000000000000000000000000000000000000000000000000000abc"]
  • description: "Change the OSM Price Source"

Targets should have the address of the governance actions address. (if inputing directly on Etherscan use quotes on the addresses)

For calldata computation there is a Node script on the computeCalls folder that works just like Seth, on the unit tests of this repo we also logged the calldatas as an example. Other tools such as Ethers.js, Web3.js, Web3.py may be used to compute the calldata. For a point and click solution use hashex. (on Etherscan do not use quotes for bytes)

Using the included script

node calldata "changePriceSource(address,address)" 0xD4A0E3EC2A937E7CCa4A192756a8439A8BF4bA91 0x0000000000000000000000000000000000000abc
0x5622b051000000000000000000000000d4a0e3ec2a937e7cca4a192756a8439a8bf4ba910000000000000000000000000000000000000000000000000000000000000abc

Using Seth:


node calldata "changePriceSource(address,address)" 0xD4A0E3EC2A937E7CCa4A192756a8439A8BF4bA91 0x0000000000000000000000000000000000000abc
0x5622b051000000000000000000000000d4a0e3ec2a937e7cca4a192756a8439a8bf4ba910000000000000000000000000000000000000000000000000000000000000abc

Here the included script is computing the call to changePriceSource with the ETH FSM as target and with the oracle address of 0x0000000000000000000000000000000000000abc

Change tokensToAuction and systemCoinsToRequest in the lender of first resort

To build a proposal to change the ``tokensToAuctionandsystemCoinsToRequest``` in the lender of first resort call the ```propose()``` function with the following params:
