Simple Summary

This SCCP proposes to remove the LEND Aggregator from the ExchangeRates contract for the migration from LEND to AAVE.

Abstract

This SCCP proposes to remove the LEND Aggregator from the ExchangeRates contract as soon as possible to prevent any further Binary option markets to be created using the LEND currencykey.

LEND is being migrated to AAVE and Chainlink will be stopping their support for the LEND-USD aggregator at 0x4aB81192BB75474Cf203B56c36D6a13623270A67.

A new aggregator for AAVE-USD prices will be added to ExchangeRates once available from Chainlink.

Motivation

The AAVE protocol has announced that LEND is migrating to AAVE.

AAVE migration

The price of LEND has become less stable as liquidity drops and many exchanges have delisted LEND pairs.

Chainlink will be removing support for the LEND-USD aggregator in the near future.
