1/ El Salvador classifying #Bitcoin as legal tender was a monumental moment
It sets the precedence that crypto can indeed be alternative to fiat and normalizes it as a tool of economic freedom
It's good for all crypto, here's how #Chainlink can help expand this even further
2/ Under this law, businesses are required to accept #Bitcoin if offered by consumers (and if they have the technical means to accept it)
However, businesses also have the option to automatically convert revieved Bitcoin into US dollars to manage their exposure risk
3/ The El Salvador government has created a $150M $USD trust fund that will purchase any #Bitcoin that businesses don't want, allowing for instant redeemability
This process and beyond will require the $BTC/USD exchange rate
You can probably see where I am going with this
4/ Use case 1: A business only wants to hold US dollars, meaning any acquired #Bitcoin will have to be sold (can't refuse the payment by law)
The government can use the cryptoeconomically secured #Chainlink BTC/USD Price Feed to execute the trade at the market-wide price
5/ While a centralized price feed for the BTC/USD exchange rate could be used, that's a central point of failure and does not follow the ethos of decentralization
Chainlink price data is available on multiple blockchains, so lower latency chains can provide more fresh data
6/ Use case 2: A business wants to price their goods and services in $USD but want/need to accept #Bitcoin if offered
At time of purchase, the #Chainlink BTC/USD Price Feed can be used to determine how much Bitcoin the consumer needs to pay in real time
7/ Use case 3: How do we know how much available USD is actually being held in the government's trust fund?
8/ The Chainlink Network is already providing Proof of Reserves for USD stablecoins $TUSD, $PAX, and $EURS, gold-backed token $PAXG, and BTC-backed tokens $WBTC and $renBTC
This data would be available for all to see and #DeFi products could even be built around this info
9/ Use case 4: Once the citizens of a nation become crypto native, the next logical step is putting that crypto to work
That's where #DeFi comes into play, it turns every crypto asset into a productive asset
10/ El Salvador is just the first domino of many in terms of nations accepting #Bitcoin as legal tender
We're already seeing politicians in other Latin America countries beginning to voice their support publicly for Bitcoin
Do not underestimate the macro narratives at play here
11/ Through the combination of #Bitcoin, #Chainlink, and #DeFi, a new decentralized, permissionless, censorship-resistant, and transparent financial ecosystem is being built before our eyes
With permissionless, compossible, and decentralized financial infrastructure, anyone can turn their tokens into productive assets
*NOTE* Nothing I describe here is risk-free, bug and hacks can happen, always DYOR before apeing
2/ The first yield opportunity is one of the newest on the street, @iearnfinance's V2 $LINK vault
This is a yield aggregation solution that automatically rebalances your funds into the DeFi protocols that earn you the highest yield on your assets, simple!
3/ If you're looking for a passive yield strategy, then this is what you're looking for
Yearn V2 vaults deploy a multi-strategy approach, where deposits are split across multiple yield protocols at the same time so as to not dilute yields once running at large scale
"@RequestNetwork has successfully integrated @Chainlink, the market leading decentralized oracle network, to enable crypto payment for invoices denominated in fiat like US dollars or Euros"
"Integrating #Chainlink’s industry leading decentralized oracle network, @DFXFinance has access to high-quality, tamper-proof price feeds needed to provide up to date FX prices to enable the most efficient AMM for Forex swapping"

2/ Keepers are essentially transaction automation bots for blockchain networks
They are crucial because smart contracts are not actually autonomous
The state of a contract can only change when it gets "poked/woken up" by an on-chain transaction or cross-contract interaction
3/ Chainlink Keepers (keeper.chain.link) is decentralized transaction automation service (starting with support for Ethereum but expanding beyond) that is far more reliable and cost-efficient than existing solutions
It is a new Chainlink Network decentralized service
TL;DR At launch $ETH will be used at the protocol level for transaction fees and bond from validators, while $LINK will be used at the app level to pay for oracle services such as Price Feeds, verifiable randomness, & L2->L1 messages
2/ An important note: Ethereum (settlement layer), Chainlink (oracles), and Arbitrum (L2 rollup) are entirely complementary technologies, each is an important piece of the puzzle that will allow for the growth of the #DeFi ecosystem at scale
Each component is needed
3/ Starting with Arbitrum's current developer documentation
$ETH will be the medium of exchange that users pay for transactions fees and is the currency staked by validators who post fraud proofs
