Mint group tokens

This method allows a group to mint new Group Circles using trusted collateral tokens. The group specifies which collateral to use and the corresponding amounts.

const groupAddress = '0xYourGroupAddress'; // The address of the group  
const collateralTokens = ['0xToken1', '0xToken2']; // Addresses of the collateral tokens  
const collateralAmounts = [BigInt(1000), BigInt(2000)]; // Corresponding amounts for each token  
const data = new Uint8Array(); // Empty data array or specific data if needed  
  
try {  
    const receipt = await avatar.groupMint(groupAddress, collateralTokens, collateralAmounts, data);  
    console.log('Minting successful:', receipt);  
} catch (error) {  
    console.error('Minting failed:', error);  
}
