Cross-chain token swaps across 54+ blockchains via Symbiosis protocol.

  • Works in 4 steps: Quote: Script calls Symbiosis API (POST… → Approve: If source token needs approval,… → Swap: Script submits the swap… → …
  • The user wants to swap
  • SKILL.md covers When To Use, Quick Start, Script Usage and Common Chains and Tokens, plus 3 more sections
  • Runs Python scripts from its folder; reaches api.bankr.bot

What it does

Symbiosis is an agent skill from BankrBot/skills. Cross-chain token swaps across 54+ blockchains via Symbiosis protocol. Use when the user wants to swap or bridge tokens between any chains — Base, Ethereum, Polygon, Arbitrum, Optimism, BNB Chain, Avalanche, Solana, Bitcoin, TON, Tron, and 40+ more. Supports any-to-any token swaps with automatic routing. Uses Bankr Submit API to execute transactions.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `catalog.json`, `references/api-reference.md` and `references/chains-and-tokens.md`).

It works with Arbitrum, Ethereum, BNB Chain and Bitcoin. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.

When your agent uses it

  • The user wants to swap
  • Bridge tokens between any chains — Base

Example prompts

  • “/symbiosis”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Quote: Script calls Symbiosis API (POST /crosschain/v1/swap) with token details and wallet address
  2. Approve: If source token needs approval, script submits an ERC20 approve transaction via POST https://api.bankr.bot/agent/submit
  3. Swap: Script submits the swap transaction via POST https://api.bankr.bot/agent/submit
  4. Track: Returns an Explorer link for cross-chain status tracking

What it can do on your machine

Read from SKILL.md and the folder at commit dc47eed. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 2 files in scripts/ (Python), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.bankr.bot

    Also links to:

    • explorer.symbiosis.finance
    • symbiosis.finance

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Symbiosis loads about 1.4k tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 91 tokens; SKILL.md has 413 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~91
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 413 words (~1,446 tokens).

“Cross-chain token swaps across 54+ blockchains. Swap any token on any chain to any token on any other chain.”
