Blockchain APIs

Proof of concept for wallet-like interactions with various blockchains.

To run examples:

npm install
node <blockchain>.js

Algorand

Pure Stake provider

Obtain an API key at Pure Stake and provide configuration in .env file:

ALGO_PURESTAKE_API=true

ALGO_API_KEY=<your-api-key>
ALGO_ALGODV2="https://testnet-algorand.api.purestake.io/ps2"
ALGO_ALGODV2_PORT=""
ALGO_IDXV2="https://testnet-algorand.api.purestake.io/idx2"
ALGO_IDXV2_PORT=""

Local private network

Pure Stake doesn't offer API for participation in consensus - this doesn't matter at all currently, since offline accounts gather participation rewards at the same rate as online accounts (the only condition is balance at least 1 ALGO).

Follow the sandbox instructions to spin up a local private network. Provide configuration in .env file:

ALGO_PURESTAKE_API=false

ALGO_API_KEY="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
ALGO_ALGODV2="http://localhost"
ALGO_ALGODV2_PORT="4001"
ALGO_IDXV2="http://localhost"
ALGO_IDXV2_PORT="8980"

Bitcoin

We use Blockbook as indexer and bitcoinjs-lib for transaction building.

Cosmos

The landscape is extremely volatile. Current latest testnet: https://stargate.cosmos.network/testnet. No faucet seems available at this moment. Follow this invite to Cosmos discord, join the Stargate testnet channel and politely ask for funds there. Keep an eye on CosmJS library for developments and documentation updates.
