Portfolio Value Tracking

The portfolio value tracking system provides real-time updates of wallet balances and token holdings. Let's examine the key components:

The sumAssets function calculates the total amount of a specific asset across UTxOs:

// src/store/slices/walletSlice.ts
// Sums assets across UTxOs for a given asset class
export const sumAssets = (utxos: St.Utxo[], assetClass: string): Big => {
  let sum = Big(0);
  for (const utxo of utxos) {
    const amountString = utxo.assets[assetClass];
    const quantity = amountString === undefined ? Big(0) : Big(amountString);
    sum = sum.add(quantity);
  }
  return sum;
};

The selectWalletLovelaceAmount selector retrieves the total lovelace amount in the wallet:

// src/store/slices/walletSlice.ts
// Selects total lovelace amount in wallet
export const selectWalletLovelaceAmount = (state: RootState): Big => {
  const utxos = state.wallet.partialWallet.utxos;
  return sumAssets(utxos, "lovelace");
};

The selectWalletAdaAmount selector converts lovelace to ADA:

// src/store/slices/walletSlice.ts
// Selects total ADA amount in wallet
export const selectWalletAdaAmount = (state: RootState): Big => {
  return lovelaceToAda(selectWalletLovelaceAmount(state));
};

Token-specific balance selectors for different assets:

// src/store/slices/walletSlice.ts
// Token-specific balance selectors for OADA, sOADA, LP tokens, and OPTIMiz
export const selectWalletOadaletAmount = (state: RootState): Big => {
  const utxos = state.wallet.partialWallet.utxos;
  const assetClass = `${oadaNetwork.oadaPolicyId}${oadaNetwork.oadaTokenName}`;
  return sumAssets(utxos, assetClass);
};

export const selectWalletSoadaletAmount = (state: RootState): Big => {
  const utxos = state.wallet.partialWallet.utxos;
  return sumAssets(
    utxos,
    `${oadaNetwork.soadaPolicyId}${oadaNetwork.soadaTokenName}`
  );
};

export const selectWalletOadaLpAmount = (state: RootState): Big => {
  const utxos = state.wallet.partialWallet.utxos;
  const lpToken = selectOadaLpToken(state);
  if (lpToken === undefined) {
    return Big(0);
  }
  return sumAssets(utxos, `${lpToken.policyId}${lpToken.tokenName}`);
};

export const selectWalletOptimizAmount = (state: RootState): Big => {
  const utxos = state.wallet.partialWallet.utxos;
  const assetClass = `${oadaNetwork.optimizPolicyId}${oadaNetwork.optimizTokenName}`;
  return assetClass ? sumAssets(utxos, assetClass) : Big(0);
};
