--- name: solana-bb11f4893ce3 slug: solana version: 1.0.0 description: Assist with Solana transactions, token accounts, priority fees, and program interactions. homepage: https://clawic.com/skills/solana metadata: clawdbot: emoji: ◎ os: - linux - darwin - win32 displayName: Solana --- ## Rent and Account Creation - Every Solana account must hold a minimum SOL balance (~0.00089 SOL for basic accounts) to be rent-exempt — accounts below this get deleted - Sending SOL to a new address that has never received anything will fail if the amount doesn't cover rent-exempt minimum - Token accounts require separate rent deposits — each new token type a wallet holds costs ~0.002 SOL to create - Close unused token accounts to recover rent: `spl-token close` returns the SOL to owner ## Token Accounts (SPL Tokens) - Unlike Ethereum, Solana wallets don't automatically hold tokens — each token needs an Associated Token Account (ATA) created first - First-time token transfers must create the recipient's ATA — sender pays ~0.002 SOL account creation fee - "Account not found" error usually means the ATA doesn't exist yet, not that the wallet is invalid - One wallet can have multiple ATAs for the same token (non-associated) — always use the ATA address for standard transfers ## Transaction Fees and Priority - Base fee is ~0.000005 SOL (5000 lamports) per signature — much cheaper than Ethereum - Priority fee = compute units × price in micro-lamports — set via `SetComputeUnitPrice` instruction - During congestion (NFT mints, popular DEX), transactions without priority fees get dropped, not queued - Default compute unit limit is 200k per instruction — complex programs may need `SetComputeUnitLimit` to increase ## Transaction Lifecycle - Solana transactions expire after ~60 seconds (based on blockhash age) — no permanent mempool like Bitcoin/Ethereum - "Dropped" means tx was never included and expired. "Failed" means it was included but reverted. Completely different outcomes - If transaction shows "confirmed" but not "finalized", wait — finalized means 31+ confirmations and is irreversible - Preflight simulation catches most errors before broadcast — disable with `skipPreflight: true` only if you know why ## Common Error Messages - "Insufficient funds for rent" — account would drop below rent-exempt minimum after transaction - "Account not found" — the account doesn't exist on-chain (never created or was closed) - "Blockhash not found" — transaction expired, need fresh blockhash and re-sign - "Program failed to complete" — smart contract error, check logs with `solana confirm -v ` ## RPC and APIs - Public RPCs (api.mainnet-beta.solana.com) have strict rate limits — production apps need paid RPC (Helius, QuickNode, Triton) - `getRecentPrioritizationFees` RPC gives current priority fee market — essential for landing txs during congestion - Solscan.io and Solana.fm are the main block explorers — both show decoded instruction data - For token metadata (name, symbol, image), query Metaplex on-chain or use Helius/SimpleHash APIs ## Wallet and Security - Phantom, Solflare, Backpack are the main wallets — each has slightly different transaction simulation UI - "Approve" prompts in Solana can drain entire wallet if malicious — read the simulation carefully - Burner wallets are common practice for minting/airdrops — never connect main wallet to unknown sites - Unlike Ethereum's infinite approvals, most Solana programs take tokens directly — no separate revoke step needed --- Source attribution: clawic Original project: https://github.com/clawic/skills/blob/f825206afbf1c697202533a9187be68c7b697e0e/skills/solana/SKILL.md License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice MIT License Copyright (c) 2026 Ivan G.
