ADDITION public RPC

Public product RPC is /rpc?cmd=getinfo on seed 34.27.30.115:38546 (site /api/rpc). Write allowlist on that port includes createwallet, mine, wallet_send, sign, tx_build (CoS). Home-node write remains 127.0.0.1:8546. Height from live getinfo may be 0.

Checking RPC…

Command explorer

Runs only public-read allowlist commands against /api/rpc. Not Ethereum JSON-RPC.

command

args

Example: getinfo

Enable the port

./build/additiond --mainnet --public-rpc --public-rpc-port 38546
# or
ADDITION_ENABLE_PUBLIC_RPC=1 ./build/additiond --mainnet --public-rpc-port 38546

Mainnet seed bind: 0.0.0.0:38546. Research testnet default remains 38545.

Talk to it

One command line in, one response line out (same as local RPC):

curl -s 'https://additionblockchain.com/api/rpc?cmd=getinfo'
curl -s 'http://34.27.30.115:38546/rpc?cmd=getinfo'
curl -s 'http://34.27.30.115:38546/jsonrpc?method=getinfo'
curl -s 'http://34.27.30.115:38546/jsonrpc?method=getblockraw¶ms=0'
printf 'getinfo\n' | nc 34.27.30.115 38546

Those curls succeed only when the operator seed answers. If they timeout, run a local --public-rpc node.

Allowlist on the site proxy (/api/rpc) for the explorer command runner (reads):

getinfo
monetary_info
crypto_selftest
tx_status <tx_hash>
peers
getblock <height_or_hash>
getblockhash <height>
getblockraw <height> (ok:BLKDATA)

On seed 38546, CoS also opened write: createwallet, mine, wallet_send, sign, tx_build / sendtx_signed*. The site wallet prefers that public path via /api/rpc, with loopback fallback.

Wallet UI: /wallet/. Desktop helper (loopback only): python3 web/addition_wallet_gui.py.

Join the public mainnet

Bootstrap P2P: 34.27.30.115:28546. Public RPC: 34.27.30.115:38546. Home-node write: 127.0.0.1:8546.

./build/additiond --mainnet --bootstrap 34.27.30.115:28546
printf 'sync\n' | nc 127.0.0.1 8546

See Get started for the full home-node recipe.

Public-read JSON API

Same allowlist on the site proxy. Not Ethereum JSON-RPC. Not a third-party dRPC vendor.

On the public-rpc port:

GET  http://HOST:38546/jsonrpc?method=getinfo
GET  http://HOST:38546/jsonrpc?method=getblock&params=0
GET  http://HOST:38546/jsonrpc?method=getblockraw&params=0
POST http://HOST:38546/jsonrpc
{"jsonrpc":"2.0","id":1,"method":"getinfo","params":[]}

Local site proxy (python3 web/serve.py): GET /jsonrpc?method=getinfo and POST /jsonrpc (default public upstream port 38546).

Standalone adapter (public-read, no writes):

python3 tools/addition_jsonrpc_adapter.py --public-read --rpc-port 38546 --port 8645
curl -s 'http://127.0.0.1:8645/jsonrpc?method=getinfo'
curl -s -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"peers","params":[]}' http://127.0.0.1:8645/jsonrpc

What stays private

Trusted write RPC: 127.0.0.1:8546 mainnet / 8545 testnet (optional ADDITION_RPC_TOKEN)
LAN RPC: off unless ADDITION_ENABLE_LAN_RPC=1 and ADDITION_LAN_RPC_TOKEN
P2P: off unless ADDITION_ENABLE_P2P_RPC=1. Operator public P2P (IPv4): 34.27.30.115:28546
Auto-mine: refused on mainnet; testnet timer only with --auto-mine / ADDITION_AUTO_MINE=1

Two local processes: two-node runbook. Website PUBLIC_RPC_HTTP is a Worker secret until an operator sets the real HTTP URL (http://34.27.30.115:38546/rpc). Do not commit trycloudflare URLs.

Do not open unauthenticated write RPC to the world (0.0.0.0:8545 / 8546). Full command list: Commands.

Fees: spec min_fee=0. last_tps and dynamic_min_fee come from getinfo when the node answers. Not a Solana/XRP speed claim. Coinbase is 50 ADD, 100% miner.
