IPFS and Milkomeda API

In addition to the Cardano ecosystem, Blockfrost also offers entry points to other ecosystems:

Network	Endpoint
InterPlanetary File System (IPFS)	`https://ipfs.blockfrost.io/api/v0/`
Milkomeda mainnet	`https://milkomeda-mainnet.blockfrost.io/api/v0/`
Milkomeda testnet	`https://milkomeda-testnet.blockfrost.io/api/v0/`

IPFS

IPFS, or InterPlanetary File System, is a distributed, peer-to-peer protocol designed for efficient and secure sharing of files and data across a global network. Is it commonly utilized for storing digital content externally from the main chain.

export BLOCKFROST_PROJECT_ID_IPFS=ipfs_YOUR_PROJECT_ID
curl "https://ipfs.blockfrost.io/api/v0/ipfs/add" \
  -X POST \
  -H "project_id: $BLOCKFROST_PROJECT_ID_IPFS" \
  -F "file=@./static/img/logo.svg"

import { BlockFrostIPFS } from "@blockfrost/blockfrost-js";

const IPFS = new Blockfrost.BlockFrostIPFS({
  projectId: "YOUR IPFS KEY HERE",
});

async function runExample() {
  try {
    const added = await IPFS.add(`${__dirname}/static/img/logo.svg`);
    console.log("added", added);

    const pinned = await IPFS.pin(added.ipfs_hash);
    console.log("pinned", pinned);
  } catch (err) {
    console.log("error", err);
  }
}

runExample();

When executed correctly, you will receive a response in JSON format, resembling the following:

{
  "name": "logo.svg",
  "ipfs_hash": "QmUCXMTcvuJpwHF3gABRr69ceQR2uEG2Fsik9CyWh8MUoQ",
  "size": "5617"
}

Milkomeda

Milkomeda is a protocol that brings EVM capabilities to non-EVM blockchains. As development progresses, Milkomeda will expand to offer L2 solutions (rollups) for several major blockchains including Cardano, Solana, and Algorand.

export BLOCKFROST_PROJECT_ID_MILKOMEDA_MAINNET=ipfs_YOUR_PROJECT_ID
curl "https://milkomeda-mainnet.blockfrost.io/api/v0/" \
   -X POST \
   -H "project_id: $BLOCKFROST_PROJECT_ID_MILKOMEDA_MAINNET" \
   -d '{"jsonrpc": "2.0", "id": 1, "method": "eth_blockNumber", "params": []}'

When executed correctly, you will receive a response in JSON format, resembling the following:

{
  "jsonrpc": "2.0",
  "id": 1,
  "result": "0xa06919"
}
