Solana Skill

Query Solana blockchain data directly via RPC endpoints. Always use CLI tools instead of browser explorers.

RPC Endpoints

Cluster	URL
Mainnet	`https://api.mainnet-beta.solana.com`
Devnet	`https://api.devnet.solana.com`
Testnet	`https://api.testnet.solana.com`

Common Operations

Get Account Info (base64)

bash

curl -s https://api.devnet.solana.com -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0", "id": 1,
  "method": "getAccountInfo",
  "params": ["<ADDRESS>", {"encoding": "base64"}]
}' | jq .

Get Account Info (parsed JSON, for token accounts)

bash

curl -s https://api.devnet.solana.com -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0", "id": 1,
  "method": "getAccountInfo",
  "params": ["<ADDRESS>", {"encoding": "jsonParsed"}]
}' | jq .

Get SOL Balance

bash

curl -s https://api.devnet.solana.com -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0", "id": 1,
  "method": "getBalance",
  "params": ["<ADDRESS>"]
}' | jq '.result.value / 1e9'

Get Recent Transactions

bash

curl -s https://api.devnet.solana.com -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0", "id": 1,
  "method": "getSignaturesForAddress",
  "params": ["<ADDRESS>", {"limit": 10}]
}' | jq '.result[] | {signature, slot, blockTime, err}'

Get Transaction Details

bash

curl -s https://api.devnet.solana.com -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0", "id": 1,
  "method": "getTransaction",
  "params": ["<SIGNATURE>", {"encoding": "jsonParsed", "maxSupportedTransactionVersion": 0}]
}' | jq .

Get Slot / Block Height

bash

curl -s https://api.devnet.solana.com -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0", "id": 1,
  "method": "getSlot"
}' | jq .result

Get Multiple Accounts

bash

curl -s https://api.devnet.solana.com -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0", "id": 1,
  "method": "getMultipleAccounts",
  "params": [["<ADDR1>", "<ADDR2>"], {"encoding": "base64"}]
}' | jq .

Decoding Anchor Accounts

Use the helper script to decode base64 account data:

bash

# Decode raw account data with field definitions
python3 .pi/skills/solana/decode_account.py \
  --data "<BASE64_DATA>" \
  --fields "discriminator:8,pubkey:32,hash:32,timestamp:i64,bump:u8"

Or fetch and decode in one step:

bash

python3 .pi/skills/solana/decode_account.py \
  --address "<ADDRESS>" \
  --cluster devnet \
  --fields "discriminator:8,coordinator:32,cert_hash:32,cert_hash_secondary:32,primary_updated_at:i64,secondary_updated_at:i64,bump:u8"

Field Types

Type	Description
`N`	N raw bytes, output as hex
`u8`	Unsigned 8-bit integer
`u16`	Unsigned 16-bit integer (little-endian)
`u32`	Unsigned 32-bit integer (little-endian)
`u64`	Unsigned 64-bit integer (little-endian)
`i64`	Signed 64-bit integer (little-endian)
`pubkey`	32-byte public key (base58 encoded)
`bool`	1-byte boolean
`string`	Borsh string (4-byte length prefix + UTF-8 data)

Quick One-Liner: Fetch + Decode

bash

curl -s https://api.devnet.solana.com -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"getAccountInfo","params":["<ADDRESS>",{"encoding":"base64"}]}' \
  | jq -r '.result.value.data[0]' \
  | python3 -c "
import base64, struct, sys
data = base64.b64decode(sys.stdin.read())
# Customize field extraction here
print('Discriminator:', data[:8].hex())
print('Field 1 (32 bytes):', data[8:40].hex())
print('Field 2 (i64):', struct.unpack('<q', data[40:48])[0])
"

Program Derived Addresses (PDAs)

To find a PDA, use the Solana CLI or compute it:

bash

# If solana CLI is installed
solana find-program-derived-address <PROGRAM_ID> --seeds "seed1" "seed2"

Or compute in Python:

python

from solders.pubkey import Pubkey
program_id = Pubkey.from_string("<PROGRAM_ID>")
pda, bump = Pubkey.find_program_address([b"seed1", b"seed2"], program_id)
print(f"PDA: {pda}, Bump: {bump}")

Token Accounts

Get all token accounts for a wallet:

bash

curl -s https://api.devnet.solana.com -X POST -H "Content-Type: application/json" -d '{
  "jsonrpc": "2.0", "id": 1,
  "method": "getTokenAccountsByOwner",
  "params": ["<WALLET>", {"programId": "TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA"}, {"encoding": "jsonParsed"}]
}' | jq '.result.value[] | {pubkey, mint: .account.data.parsed.info.mint, amount: .account.data.parsed.info.tokenAmount.uiAmount}'

Tips

•Always use CLI over browser - faster, scriptable, no cookie dialogs
•Use jq for filtering - extract just what you need
•Check cluster - devnet/testnet/mainnet have different data
•Rate limits - public RPCs have limits; use paid RPC for heavy usage
•Base58 vs Hex - Solana addresses are base58; account data is often hex/base64
