A DeFi Vector has a source address and a destination address. The source address is controlled by the vector agent (canister). The destination address can be anywhere and doesn’t have to be controlled by the agent. Vectors are first set up inside the agent and then used simply by sending tokens t…

Interesting stuff. I read it a couple of times - hopefully I’m on the same page in thinking. The first thing that pops into my head with this kind of thing is a tax efficient way of taking payments. A business could have a payment vector which takes payments in any token, converts this to a USD sta…

Sounds like an interesting use case! Thanks for sharing. Defi Vectors only specify some transport & communication aspects. Rule 1: Vector agents aren’t required to be called/notified with messages when receiving tokens for their casual operation, transfering to the source address is sufficient and…

There is a slight problem. ICRC ledgers accept tx with {account;subaccount} and log tx with {account;subaccount} The ICP ledger accepts tx with {account;subaccount} or (legacy account) and log tx with (legacy account) legacy account - hash({account;subaccount}) With the ICP ledger when following…

DeFi Vector throughput Please let me know if there is a flaw in the following calculations: Given there is a backpressure limit - up to 500 in-flight calls between a pair of canisters. If a single icrc1_transfer takes 5 seconds, that will mean a canister can make up to 100 calls/sec = 100 tx/s wit…

We have a PoC permanent exchange vector working https://github.com/Neutrinomic/defivectors Not audited yet, it’s under development. Going through the whole code to see how they work isn’t recommended. Also we want to make more vectors and do the airdrop with one and a lot of the code can be reused…

[image] infu: So in theory, a DeFi vector has a limit of sending 10,000 tx/s with ICRC-4 , reading 5,000 tx/s with ICRC-3 and a limit of sending 100 tx/s with ICRC-1. The test confirmed it DeVeFi Ledger - ICRC ledger client library - #11 by infu

Some more advanced things you can do with ICP DeVeFi using our MIT-licensed library. All kinds of DeFi contracts—you just program the flow and nothing else. Contract size reduced from ~5000 lines to 50. Lending, AMMs, arbitrage bots, trading bots, algorithmic coins, etc. You send one token, you get …

Yes, if a canister method doesn’t have “icrc” prefix then it is not part of any icrc. Ledgers will have icrc1,2,3,4 and so on methods. Our middleware is currently made to only work with the SNSW icrc ledger by Dfinity, but we will make it work with icrc3 when it gets implemented.
