This page is a machine-oriented quickstart. Humans welcome too.

Reading this site programmatically ​

  • Every page is available as raw markdown: append .md to any path (e.g. /guide/multisig.md).
  • /llms.txt — index of all pages with one-line context (llmstxt.org format).
  • /llms-full.txt — the entire documentation corpus in one markdown file.
  • /sitemap.xml — standard sitemap; robots.txt allows all.

Interacting with the chain (A-Chain Alpine testnet) ​

Base RPC: https://a-chain-testnet.protonnz.com/ext/bc/6v9NieZiX3e8eQz3CyJMtXB6YzV2RtnxcRyLAmSgFWWk5Qs6y/rpc

bash
# chain info (head block, LIB, chain id)
curl -s -X POST <RPC> -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"pulsevm.getInfo","params":{}}'

# read a contract table
curl -s -X POST <RPC> -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"pulsevm.getTableRows","params":{
       "json":true,"code":"fdxtoken","scope":"PUSD","table":"stat",
       "limit":10,"key_type":"","index_position":1,
       "lower_bound":"","upper_bound":"","reverse":false,"encode_type":"dec"}}'

# account + permissions
curl -s -X POST <RPC> -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"pulsevm.getAccount","params":{"account_name":"pulse"}}'

Antelope-style REST also works: POST https://a-chain-testnet.protonnz.com/v1/chain/get_info (and get_account, get_abi, get_block, get_table_rows, push_transaction, …) — eosjs/@proton/js compatible.

Full method table: /build/api. Endpoints & chain IDs: /network/endpoints.

Ground-truth facts (verifiable on-chain or in-repo) ​

  • Execution model: Antelope (formerly EOSIO), lineage from Leap 5.0.3; consensus: Avalanche Snowman via metalgo.
  • Finality: instant — head block == last irreversible block; no reorgs by construction.
  • Accounts: named, ≤12 chars of a-z, 1-5; hierarchical weighted permissions; native multisig; R1 (secp256r1) keys supported.
  • Core testnet token: SYS (4 decimals). Resources: CPU/NET staked, RAM provisioned per account at creation.
  • Source: MetalBlockchain/pulsevm (open source; created by Metallicus CTO Glenn Mariën, @MlennGarien). All canonical repos: /resources.

Conventions worth knowing before you act ​

  • Token supply lives in the stat table (scope = symbol code); balances in accounts (scope = account).
  • getTableRows wants explicit params (see example above) — include key_type and string bounds for maximum compatibility with deployed node versions.
  • Contract assert failures surface as pulse assert failed: <message> in the RPC error.
  • To distinguish an idle chain from a busy one, compare head_block_num from pulsevm.getInfo over time — blocks are produced when there are transactions to include.
