Zerion — Trading

Execute on-chain trading actions: swap, bridge, send. All commands build, sign, and broadcast a transaction in one shot using the active agent token as the signer passphrase.

Setup

If a zerion command fails with command not found, install once:

npm install -g zerion-cli

Requires Node.js ≥ 20. For auth see the zerion umbrella skill. All trading needs an API key + agent token. Pay-per-call (--x402, --mpp) does NOT apply here.

When to use

• "Swap X for Y" / "convert tokens" / "trade"
• "Bridge X to chain Y" (cross-chain)
• "Send tokens to address" (native ETH/SOL or ERC-20)

For balance checks before trading → zerion-analyze. For setting up an agent token → zerion-agent-management. For off-chain signing (permits, EIP-712) → zerion-sign.

Pre-flight

zerion wallet list                       # confirm wallet exists, see active policies
zerion agent list-tokens                 # confirm agent token is set

If no agent token, the CLI offers an inline create-token prompt on the next trade attempt (TTY only). In CI / piped contexts, see zerion-agent-management.

Swap (same-chain)

Convert one token to another on the same chain. For cross-chain conversion use bridge.

# zerion swap <chain> <amount> <from-token> <to-token>
zerion swap base 1 USDC ETH
zerion swap ethereum 0.1 ETH USDC
zerion swap arbitrum 100 USDC DAI

# Solana same-chain swap
zerion swap solana 0.1 SOL USDC

# Specific wallet (overrides defaultWallet)
zerion swap base 1 USDC ETH --wallet <name>

# Custom slippage (default 2%, max 3%)
zerion swap base 1 USDC ETH --slippage 3

# Confirmation timeout (default 120s)
zerion swap base 1 USDC ETH --timeout 300

Tokens accepted as: symbol (ETH, USDC, SOL), 0x address (EVM), Solana mint, or full search match. Prefer the explicit address when the symbol is ambiguous.

# List swap-available tokens for a chain
zerion swap tokens                       # all chains
zerion swap tokens base                  # filter to Base
zerion swap tokens solana                # filter to Solana

Bridge (cross-chain)

Move (and optionally swap) tokens between chains. Bridge with the same token on both sides for a pure transfer; pass a different to-token for bridge + swap.

# zerion bridge <from-chain> <from-token> <amount> <to-chain> <to-token>

# Same-token bridge between EVM chains
zerion bridge base USDC 5 arbitrum USDC
zerion bridge ethereum USDC 100 polygon USDC

# Bridge + swap on destination
zerion bridge base USDC 5 arbitrum ETH

# Native token bridge
zerion bridge base ETH 0.001 optimism ETH

# Bridge EVM → Solana (mnemonic wallet has both accounts → no extra flag needed)
zerion bridge ethereum USDC 50 solana USDC

# Bridge Solana → EVM
zerion bridge solana USDC 50 ethereum USDC

# Cross-format bridge to a different local wallet
zerion bridge ethereum USDC 50 solana USDC --to-wallet <sol-wallet>
zerion bridge solana USDC 50 ethereum USDC --to-wallet <evm-wallet>

# Bridge to a raw destination address (must match the target chain's format)
zerion bridge ethereum USDC 50 solana USDC --to-address <solana-pubkey>
zerion bridge solana USDC 50 ethereum USDC --to-address 0x...

# Slippage / timeout flags work the same as swap
zerion bridge base USDC 5 arbitrum ETH --slippage 3 --timeout 300

Cross-chain destination rules

For Solana ↔ EVM bridges (different address formats), the destination receiver is resolved in this priority order:

1. --to-address <addr> — raw recipient. Must match the target chain's format (0x… for EVM, base58 pubkey for Solana). ENS names allowed for EVM.
2. --to-wallet <name> — local wallet whose corresponding account on the target chain is used.
3. Fallback — the source wallet itself, if it has an account on the target chain (true for any mnemonic-derived wallet).

The destination wallet must have an account that satisfies the target chain. EVM-only wallets cannot receive on solana; Solana-only wallets cannot receive on EVM chains.

If the API returns swap cannot be performed with the given parameters, the route doesn't currently exist for the requested pair. Verify the token has implementations on both chains (zerion search <symbol>), try a different amount, and confirm both chains support bridging (zerion chains).

Send (transfer)

Native + ERC-20 + native SOL transfers. --chain is auto-inferred from the recipient address format when not passed (0x… → ethereum default, base58 → solana).

# EVM: native + ERC-20
zerion send ETH 0.01 --to 0x... --chain base
zerion send USDC 10 --to vitalik.eth --chain ethereum

# Solana: native SOL (chain auto-detected from base58 recipient)
zerion send SOL 0.1 --to 2Nsnn…
zerion send SOL 0.1 --to 2Nsnn… --chain solana   # explicit form

Recipients accepted: 0x address (EVM), ENS name (resolved at send time), Solana base58 pubkey. SPL token sends on Solana are not yet supported via the CLI — convert to SOL first with zerion swap solana <amount> <token> SOL.

Token search (resolve symbols → addresses)

zerion search <query>                    # by name, symbol, or address
zerion search PEPE --chain ethereum
zerion search "uniswap" --limit 5

Chain validation

zerion chains                            # full chain catalog

Use this to confirm a chain ID is supported before passing --chain / --to-chain / --from-chain.

Output & global flags

Flag	Description
--wallet <name>	Source wallet (default: from config)
--to-wallet <name>	Destination wallet for bridge (Solana ↔ EVM)
--to-address <addr>	Destination address for bridge (chain-format must match destination chain)
--to <addr>	Recipient address for send
--slippage <pct>	Slippage tolerance (default 2%, max 3%)
--timeout <sec>	Confirmation timeout (default 120s)
--json / --pretty / --quiet	Output mode (JSON default)

Pre-trade safety checklist

1. Confirm the agent token is bound to the right wallet — zerion agent list-tokens shows wallet bindings.
2. Confirm policy allows the action — zerion agent list-policies (e.g. --deny-transfers blocks raw send; --chains base blocks swaps on other chains).
3. Slippage — defaults to 2%. Tight (0.5%) for stable pairs, loose (3-5%) for low-liquidity tokens.
4. Cross-chain timeout — bridges can take 1-5 min. Use --timeout 300 for slower routes.

Common errors

Code	Cause	Fix
no_agent_token	Trading needs an agent token	zerion-agent-management skill
policy_denied	Action blocked by an active policy	Check agent show-policy <id>; revise or use unrestricted token
unsupported_chain	Invalid chain	zerion chains
insufficient_balance	Not enough of <from-token>	zerion portfolio --wallet <name> to check
quote_failed	No route between tokens / chains	Try a different pair or chain
slippage_exceeded	Price moved beyond --slippage	Increase slippage or retry
tx_timeout	Confirmation didn't land within --timeout	Bump timeout, check tx hash on explorer
invalid_destination	Cross-chain destination missing or wrong format	Pass --to-wallet <name> or --to-address <addr> matching the --to-chain format
