TrueHold reads that address on every EVM chain it covers and puts the results in one total: tokens priced where markets exist, DeFi positions decoded by protocol, NFTs at floor price and marked as floor. Rainbow’s own RNBW token, launched in February 2026, is counted like any other token at market.

How it connects

  1. 01

    Copy the address

    In Rainbow, tap Copy on the wallet screen. For a QR code, open the menu at the top right and choose My QR Code.

  2. 02

    Paste it into TrueHold

    One 0x address is read across Ethereum, Base, Arbitrum, Optimism, Polygon and the other EVM chains TrueHold covers.

  3. 03

    See every chain at once

    Tokens, DeFi positions and NFTs from every chain the address has touched land in one view, priced live.

What you will see

One address, many chains
Ethereum, Base, Arbitrum, Optimism, Polygon and the rest, read from a single 0x address.
DeFi positions decoded
Lending, liquidity and staking positions labelled by protocol, not left as raw balances.
NFTs at floor
Collections valued at floor price and marked as floor, so the total does not lean on hope.
Nothing connected
No wallet session and no signature: the address is all TrueHold needs.

Questions people ask

No. Copy the address and paste it. Rainbow is never connected and nothing is signed.

Every EVM chain TrueHold reads, including Ethereum, Base, Arbitrum, Optimism, Polygon and BNB Chain. The address is the same on all of them.

Rainbow’s supported networks are EVM chains, so there is one 0x address to paste. Bitcoin or Solana kept in another wallet is added from that wallet’s address.

Yes. Pasting addresses and seeing balances, history and PnL costs nothing. Premium exists for the extras, tax-ready CSV exports above all, and nothing about plain tracking sits behind it.

Continuously. TrueHold re-reads each address on a rolling schedule, so on-chain moves appear within minutes and valuations follow live prices in between.

Paste them all. Each address is read separately and totalled together, which is how most real setups look once a wallet has been in use for a while.

Your sign-in details, the addresses you paste and the public data behind them. TrueHold does not try to work out who owns an address, and an address gives no control over funds. The privacy policy lists what is collected.
