Hi everyone :waving_hand: Summary As announced in the Global R&D of January 2025 , DFINITY is working on a Solana RPC canister that will leverage HTTPs outcalls to interact with the Solana blockchain. This canister will be managed as a service (under NNS control) and will extend the Chain Fusion ca…

Hi everyone :waving_hand: It’s with great pleasure that I can announce that we released today the first version of the SOL RPC canister :rocket: . v0.1.0 This is a pre-release, currently deployed on a staging canister ( titvo-eiaaa-aaaar-qaogq-cai ) on the fiduciary subnet ( pzp6e ). The only differe…

I remember the mention of a difficulty with Solona RPC being that the hash needed to write a transaction was difficult to get through the RPC due to response times and the 13 nodes getting different responses. Was this issue resolved and/or what is the best way to mediate it? Is there a suggested …

Hi @skilesare ! Your questions should be answered by the README and the basic_solana example but feel free to follow-up if that’s not the case.

Question: Will the slot passed away already after we getSlot and then send out the transaction? There are therefore two options to send a transaction on Solana using the SOL RPC canister. Use a durable nonce instead of a blockhash. Retrieve a recent blockhash by first retrieving a recent …

Hi @0xkookoo ! Could you clarify what you mean with Will the slot passed away ?

Hey I’ve already built a fully on-chain cross-chain bridge on ICP, enabling secure and decentralized transfers: EVM to EVM EVM to Solana EVM to Stellar All key processes — from transaction construction, signature generation (ECDSA/Ed25519), on-chain indexing, and relaying — are handled entirely …

@gregory-demay Hello，thanks for your amazing work on sol-rpc-canister, I’m integrate the canister with our canisters. I found that the interface named getTransaction is not support the JsonParsed encoding. Could you let me known why? If you are working on it, when can the interface support the Json…

@StewartYe Thank you for your interest in the SOL RPC canister! That’s correct, we currently don’t support the jsonParsed or json encodings for the getTransaction endpoint primarily because of their limited support with the Rust Solana SDK (see e.g. here ). Using a binary encoding (i.e. base58 or bas…

Ok, thanks. I resovled it. I implemented the parse logic to do it.

Another, I found that SOL-RPC-CANISTER is pre-release and deplyed on staging environment only now, When will you deploy it on production environment?

We’ve integrated Solana, along with Stellar and EVM chains (testnet), into Kosh Wallet. The indexer runs fully on-chain within ICP canisters, and signing is done using threshold cryptography.
