I have experience with Blockful - I’ll link to the comments I made on their initial proposal. [RFP] Develop a Keyper Incentive Mechanism and (delegated) Staking - Blockful - #2 by 5pence
I’d also like to add that when the social proposal for the 3 million DSR deposit passed, I asked Blockful if they wanted to support 0x36 by helping to research and craft the executable proposal for the transfer.
They researched the best ways to perform the 3million USDC → DAI → Deposit safely using PSM swaps, ensuring the deposit function was properly crafted. It went smoothly.
