# Cross-Chain Real World Asset Tokenization

Any developer can create, register, and mint Real World Assets natively on any chain supported by the pigeons in the Paloma Validator set.

On all chains, Paloma Validators monitor an ERC-20 Factory contract called the ETF Purchaser Contract that handles creation of ERC-20 stock token that corresponds to a Real World Asset on the PalomaDex API.

# Create a Real World Asset Token

  • Write to the ETF Purchaser Contract using the create_signle_etf function. (the spelling in signle is deliberate)
  • Inputs to the function are:
    • _token_name
    • _token_symbol
    • _token_description
    • _etf_ticker
    • _expense_ratio (the expense ratio is for ETF tickers only)

# Buying a Real World Asset Token (Minting step)

  • Write to the ETF Purchaser Contract using the buy payable function. Inputs to the payable function are as such:
    • A user can buy with ETH or any token which listed on Uniswap v3 and Curve
    • _etf_token The etf_token address is the token the user will purchase.
    • _etf_amount The token amount
    • _recipient The recipient EVM address
    • _path The path for swapping the input token into USDT. We use Uniswap v3 and then Curve for swap paths on all target chains.
    • _min_amount The default is 0 (it's for the min amount for swapping into USDT)

PURCHASE SETTLEMENT NOTE: Real World Assets Purchased will be verified off-chain with Paloma's custodians that funds are received. Once funds are received on the target chain, the asset will mint.

# Selling a Real World Asset Token (Redeem or Burning Step)

  • Write to the ETF Purchaser Contract using the sell external function. Inputs to the external function are as such:

    • _etf_token This address is the token the seller wants to sell
    • _etf_amountThe token amount
    • _estimated_amount The estimated PalomaUSD (PUSD) amount after sell. Developers can get estimated amount from the etfapi/v1/customindexprice api on PalomaDex.
    • _recipient: The recipient's EVM address

    SELLERS SETTLEMENT NOTE: Real World Assets sold are redeemed for PalomaUSD (PUSD) stablecoin on all target chains. Any user can withdraw PUSD for USDT on any target chain. Also, any user can redeem PUSD for USDT on https://www.palomadex.com/ (opens new window) using Buy/Sell to sell PUSD to receive USDT.

# Target Chains For Cross-Chain Real World Asset Tokenization

All blockchains listed below are currently supported by Paloma's relay pigeons and allow for remote message execution. Token prices are identified by ticker symbol and covers stocks, ETFs, currencies, as well as crypto assets. New blockchains will be added by the validator set as Paloma community votes them into governance.
