Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.01399 |
| Opus 5.5 | $0.00023 | $0.00560 |
| Sonnet 5.5 | $0.00011 | $0.00280 |
| Haiku 4.5 | $0.00006 | $0.00140 |
Grade A, and why
solana scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Solana signing
This skill exposes a small foundation for building unsigned Solana transactions from chat. The plugin never sees a Solana private key — every state-changing tool returns a base64-encoded VersionedTransaction that the user signs in their wallet.
When to use this skill
- The user asks to "send SOL to X" or "transfer USDC to Y" from a Solana address they control.
- The user wants to inspect a Solana transaction someone else built before signing it.
- A more advanced Solana flow (Drift order, Marginfi deposit, Kamino borrow) builds on the foundation here — when those land, they will reuse
lib/solana-sign.tsdirectly.
What the surface is
chaingpt_solana_build_transfer_tx— build an unsigned transfer.- Native SOL when
mintis omitted. Decimals: 9 (LAMPORTS_PER_SOL). - SPL Token (classic or Token-2022) when
mintis provided. Decimals fetched from the mint account. Source + destination Associated Token Accounts derived automatically. IdempotentCreateATAIdempotentinstruction included so first-time-recipient transfers work without an extra setup step. acknowledgeMainnet: truerequired whennetwork=mainnet. Same gate as the EVM tools.
- Native SOL when
chaingpt_solana_decode_tx— decode an unsigned base64 versioned transaction for review (payer, blockhash, instruction count, program ids with annotations).
Custody model
Identical to the rest of the plugin: custody-free. The plugin builds the transaction; the user signs it elsewhere. There is no MCP tool that accepts a secretKey, mnemonic, or seedPhrase parameter, and a unit test asserts this surface contract so future additions cannot accidentally break it.
If the user wants policy-gated signing (agent wallet pattern), the existing agent wallet skill provides that for EVM. A Solana counterpart is queued as a follow-up to this foundation.
Mainnet safety gate
When network=mainnet, the build tool refuses unless acknowledgeMainnet=true is also passed. The refusal message lists what to verify before re-call (recipient address, amount, mint, network). This matches feedback_mainnet_default: mainnet is the target, but mainnet transactions require an explicit ack.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

solana is a skill published in the GitHub repository ChainGPT-org/chaingpt-claude-skill (7 stars, last pushed 1mo ago), licensed MIT. It adds 57 tokens to every session and 1,399 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
