❓ About IPFS W3Auth Pinning Service

✨ Usage

The IPFS W3Auth Pinning Service(aka. W3Auth PS) is compatible with standard IPFS remote pinning service. You can refer IPFS Docs to learn how to use remote pin.

As for the Access Token of W3Auth PS, you can easily get it with several web3 ways.

Authorization: Bear <base64(ChainType-PubKey:SignedMsg)>

Let's take ipfs cli as an example

ipfs pin remote service add crustpinner http://localhost:3000/psa base64(ChainType-PubKey:SignedMsg)

Get ChainType

ChainType now can be:

1. sub(or substrate)
2. eth(or ethereum)
3. sol(or solana)
4. pol (or polygon)
5. nea (or near)
6. ava(or avalanche)

And you can get PubKey and SignedMsg by using the following web3-ways:

1. With Substrate

Get PubKey

PubKey is just the substrate address, like 5Chu5r5GA41xFgMXLQd6CDjz1ABGEGVGS276xjv93ApY6vD7

7. With Avalanche

You can sign the Address without chainID prefix, such as avax1se4e9lvhlfwhcqnzjr0vpswqcnhsy5atn5r0l3, with your X- or P- chain private key associated with your account to get the SignedMsg.

• With Avalanche Wallet
