Querying THORChain
How to Query THORChain
Vaults are fetched from the
/inbound_addresses :You need to select the address of the Chain the inbound transaction will go to.
The address will be the current active Asgard Address that accepts inbounds. Do not cache these address as they change regularly.
Example Output, each connected chain will be displayed.
[
{
"address": "bc1q2taly7tynxvmmw5n2048wv56cyhmnc6lvx7737",
"chain": "BTC",
"chain_lp_actions_paused": false,
"chain_trading_paused": false,
"dust_threshold": "10000",
"gas_rate": "19",
"gas_rate_units": "satsperbyte",
"global_trading_paused": false,
"halted": false,
"outbound_fee": "39000",
"outbound_tx_size": "1000",
"pub_key": "thorpub1addwnpepq22rph4ed3nkp6lp060nmuqy3p0axadaklnvcs4qfrgyq6zl0rrux9jxkxj"
},
...
]
If a chain has a
router on the inbound address endpoint, then everything must be deposited via the router. The router is a contract that the user first approves, and the deposit call transfers the asset into the network and emits an event to THORChain.
This is done because "tokens" on protocols don't support memos on-chain, thus need to be wrapped by a router which can force a memo.
Note: you can transfer the base asset, eg ETH, directly to the address and skip the router, but it is recommended to deposit everything via the router.
{ "address": "0x500b62a37c1afe79d59b373639512d03e3c4f5e8",
"chain": "ETH",
"gas_rate": "70",
"halted": false,
"pub_key": "thorpub1addwnpepq05w4xwaswph29ksls25ymjkypav30t8ktyu2dqzkxqk3pkf2l5zklvfzef",
"router": "0xD37BbE5744D730a1d98d8DC97c42F0Ca46aD7146"
}
If you connect to a public Midgard, you must be conscious of the fact that you can be phished and could send money to the WRONG vault. You should do safety checks, i.e. comparing with other nodes, or even inspecting the vault itself for the presence of funds. You should also consider running your own 'fullnode' instance to query for trusted data.
Never cache vault addresses, they churn regularly.
Check for the
halted parameter and never send funds if it is set to trueChain: Chain NameAddress: Asgard Vault inbound address for that chain., Halted: Boolean, if the chain is halted. This should be monitored.gas_rate: rate to be used, e.g. in Stats or GWei. See Fees.Use the
/pools endpoint of Midgard to retrieve all swappable assets on THORChain. The response will be an array of objects like this:{
"asset": "BNB.BTCB-1DE",
"assetDepth": "11262499812",
"assetPrice": "11205.698400479405",
"assetPriceUSD": "38316.644098172634",
"liquidityUnits": "61816750778660",
"poolAPY": "0.24483254735655713",
"runeDepth": "126204176128728",
"status": "available",
"synthSupply": "0",
"synthUnits": "0",
"units": "61816750778660",
"volume24h": "67544420820530"
}
Only pools with
"status": "available" are available to tradeMake sure to manually add Native $RUNE as a swappable asset.
"assetPrice" tells you the asset's price in RUNE (RUNE Depth/AssetDepth ). In the above example1 BNB.BTCB-1DE = 11,205 RUNEAll values on THORChain (thornode and Midgard) are given in 1e8 eg, 100000000 base units (like Bitcoin), and unless postpended by "USD", they are in units of RUNE. Even 1e18 assets, such as ETH.ETH, are shortened to 1e8. 1e6 Assets like ETH.USDC, are padded to 1e8. THORNode will tell you the decimals for each asset, giving you the opportunity to convert back to native units in your interface.
See code examples using the THORChain xchain package here https://github.com/xchainjs/xchainjs-lib/tree/master/packages/xchain-thorchain
There are two ways to see if a Chain is halted.
- 1.
- 2.
