Supported Chains

Prysm auto-detects the chain from a pasted contract whenever the address format is unique to one chain — Solana, TON, TRON, and Sui all have distinctive shapes. EVM addresses (0x followed by 40 hex characters) look identical across Ethereum, Base, BSC, Polygon, Arbitrum, Optimism, Avalanche, and MegaETH, so for those you either pick the chain from the disambiguation prompt or specify it explicitly with a shortcut.

Every chain at a glance

Chain	Shortcut(s)	Address format	Native token	Notes
Ethereum	`/eth`, `/ethereum`	`0x` + 40 hex	ETH	EVM; ATH lookup supported
Base	`/base`	`0x` + 40 hex	ETH	EVM; ATH lookup supported
BSC	`/bsc`, `/bnb`	`0x` + 40 hex	BNB	EVM; ATH lookup supported
Polygon	`/polygon`, `/matic`	`0x` + 40 hex	MATIC	EVM; ATH lookup supported
Arbitrum	`/arb`, `/arbitrum`	`0x` + 40 hex	ETH	EVM; ATH lookup supported
Optimism	`/op`, `/optimism`	`0x` + 40 hex	ETH	EVM; ATH lookup supported
Avalanche	`/avax`, `/avalanche`	`0x` + 40 hex	AVAX	EVM; ATH lookup supported
MegaETH	`/mega`, `/megaeth`	`0x` + 40 hex	ETH	EVM; ATH not available
Solana	`/sol`, `/solana`	base58, 32–44 chars	SOL	Pre-migration pump.fun bonding-curve pairs supported in `/og`
Sonic	`/sonic`	`0x` + 40 hex	S	ATH not available
TON	`/ton`	`EQ…` / `UQ…` + 46 chars	TON	ATH not available
Tron	`/tron`, `/trx`	`T` + 33 base58 chars	TRX	ATH not available
Sui	`/sui`	`0x` + 64 hex, optional `::module::name` suffix	SUI	ATH not available

The shortcut commands are interchangeable with each other — /eth and /ethereum both filter your watchlist to Ethereum tokens. They also work as chain hints in front of a contract: /sol <ca>, /eth <ca>.

Address formats

These are the exact patterns Prysm matches when you paste a contract. If your input doesn’t match one of them, auto-detect won’t fire — you’ll need to use /add with an explicit chain shortcut.

Format	Pattern	Example
EVM	`0x` followed by 40 hex characters	`0x6982508145454ce325ddbe47a25d4ec3d2311933`
Sui	`0x` followed by 64 hex characters, optionally `::module::name`	`0x2::sui::SUI`
TON	`EQ` or `UQ` followed by 46 base64url characters	`EQCxE6mUtQJKFnGfaROTKOt1lZbDiiX1kCixRv7Nw2Id_sDs`
Tron	`T` followed by 33 base58 characters	`TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t`
Solana	32–44 base58 characters (no prefix)	`EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v`

EVM is the only format that’s ambiguous — every other shape uniquely identifies its chain. So pasting a Solana mint, a TON jetton, a Tron TRC-20, or a Sui coin type goes straight to “added” without asking.

How auto-detect resolves a paste

When you paste a string, Prysm runs the patterns above in this order:

EVM (0x + 40 hex) — held aside as ambiguous, then checked against every EVM chain Prysm tracks.
Sui (0x + 64 hex, optional ::module::name).
TON (EQ / UQ prefix).
Tron (T prefix, 34 chars total).
Solana (any base58 string 32–44 chars).

If none of the above match, the message is ignored — auto-detect is deliberately strict to avoid false positives on regular chat text.

Caveats and chain-specific behaviour

All-time high is EVM-only. /ath works on Ethereum, Base, BSC, Polygon, Arbitrum, Optimism, and Avalanche. On any other chain the bot will tell you ATH isn’t supported. MegaETH is EVM but isn’t covered for ATH either.
Solana auto-detect covers pre-migration pump.fun pairs. When /og runs against a Solana symbol, bonding-curve pump.fun pairs are treated as real even if standard liquidity reads as null. See the filtering rules for the full list of exemptions.
EVM disambiguation. A 0x… address could live on any of eight chains. Two ways to resolve it:
- For /add — paste the contract. Prysm checks every EVM chain it tracks and adds the token from the first chain where it has a real pair. There’s no chain-prefix syntax for /add itself.
- For /og — pass the chain shortcut as the first argument so the lookup is pinned to one chain:
```
/og eth 0x6982508145454ce325ddbe47a25d4ec3d2311933
/og base 0x6982508145454ce325ddbe47a25d4ec3d2311933
```
  Works for every EVM shortcut (mega, arb, etc.). If the shortcut doesn’t recognise the address on that chain, Prysm tells you instead of silently picking a different one.
Address case. Solana, TON, and Tron addresses are case-sensitive — paste them exactly as you copied them. EVM and Sui addresses are normalized to lowercase internally, so case doesn’t matter for those.
Sui type-tag suffixes. A Sui coin reference can include the ::module::name tail (e.g. 0x2::sui::SUI). Prysm accepts both forms — the bare 64-hex package address and the full type tag — and resolves them to the same coin.

Filtering your watchlist by chain

Every shortcut doubles as a list filter. From DM:

/sol — only your Solana tokens
/eth — only your Ethereum tokens
/base, /bsc, /polygon, /arb, /op, /avax, /mega, /sonic, /ton, /tron, /sui — same idea per chain

The same shortcuts can scope other lookups too. For example:

/ath eth — all-time high view restricted to your Ethereum tokens
/og sol PEPE — find the original PEPE on Solana
/bag eth — bag-cost view restricted to your Ethereum tokens

If you pass a shortcut that the command doesn’t support (e.g. /ath ton), Prysm replies with the list of chains it does support for that command rather than failing silently.
