+# Serai
+
+Serai is a fairly launched cross-chain decentralized exchange, integrating
+Bitcoin (BTC), Ethereum (ETH, DAI), and Monero (XMR).
+
+The Serai mainnet has yet to launch, and until then, all details are subject to
+change.
+
+Prior to the Serai mainnet launching, SRI, Serai's native coin, will not
+exist. As a fairly launched project, SRI will have no ICO, no IEO, no presale,
+no developers' tax/fund, and no airdrop for out-of-mainnet activity.
+
+Out-of-mainnet activity includes:
+
+- Being a community member (such as on Discord or on Twitter)
+- Participating in testnets
+- Contributing to the GitHub
+
+None of these will be awarded any airdrop. All distributions of SRI will happen
+on-chain per the protocols' defined rules, based on on-chain activity.
